# Oriel

**Oriel** is a design system; what it is for is not recorded yet (Q-scope-01).

- **For:** people who use it often, as an everyday app
- **Screens:** pages people read
- **Runs on:** web
- **Feel:** warm, refined (friendly, premium; picked for you)
- **Brand color:** Picked for you, not chosen by you: a brown (#B4532A) on buttons, links and focus, with white text that reads clearly on it.
- **Decided:** 8 picked for you; everything else uses sourced defaults
- **Standards:** 289 house standards followed (locked, house standards v2); see the Standards section
- **Next:** zoom into Colors, Typography, Layout, or stop here: each level works
- **Licence risks:** none found

> Generated by the OpenDesigner engine 1.0.0 from `opendesigner/state.json` and `opendesigner/decisions.md`; `opendesigner/tokens/` is the source of truth. Change the system with `engine.py set ...` and `engine.py build`, not by editing this file (notes inside `<!-- od:keep -->` blocks survive). Each section opens with one plain sentence; open **More** for the designer and engineer detail.

**Oriel feels friendly and premium. Screens are roomy, in a flat style.**
Designers: visual style: flat, tonal, glass · Code: `preset in state.json`

<details><summary>More</summary>

**Your answers here** (each one either sets tokens or is a rule for this section):
- What are these screens mostly for: selling, getting work done, reading, or enjoying an experience? **Read** (delegated; tokens; Q-scope-06)

**Intent.** A design system generated from eight dials and a few raw inputs.

- Audience: people who use it often, as an everyday app
- The memorable thing: not recorded yet (Q-brand-02)
- Surfaces: pages people read
- Platforms: web; inputs: pointer, touch
- Direction: preset flat2 (the default until Q-dir-01 is answered); feel friendly, premium (words picked for you: warm, refined)

**Principles (ranked).**
No principles recorded yet (Q-brand-07). Until they are, the dials act as the tie-breakers below.

**Dial positions.** Three posture dials set the overall stance. Five character dials fine-tune it.

- **Expression 62/100** (productive to expressive: leaning expressive): type ratio 1.25, hero moments: significant-moments, expressive motion: significant-moments, brand color role: accent+signature-surface, containment: mixed.
- **Brand presence 62/100** (native to brand-led: leaning brand-led): typeface suggestion: open-custom-face, brand color placement: accent+signature-surface, native component share about 61%, voice guidance: short.
- **Density 32/100** (spacious to compact: spacious): body 16px on the web, default control 48px, density mode spacious, icons 24px; hit areas never shrink.
- **Energy 30/100** (calm to energetic: calm): standard easing [0.77, 0, 0.175, 1], duration multiplier 0.92, spring damping 1.0, heading weight 600, navigation: recessive.
- **Roundness 64/100** (sharp to soft: leaning soft): control radius 12, icon corners rounded, caps round.
- **Depth 45/100** (flat to deep: balanced): depth model: tonal.
- **Colorfulness 38/100** (monochrome to vivid: leaning monochrome): scheme tonalSpot, accent chroma 52.2 (HCT), 1 accent(s), surfaces: neutral+one-accent.
- **Warmth 88/100** (cool/formal to warm/friendly: warm/friendly): neutral tint chroma 0.017 at hue 43, borders: soft, sentence-case, contractions encouraged.

**Zoom by area** (sketch, broad, defined, detailed). You can stop at any level; each one works.

## Colors

> Zoom: sketch (0 of 3), 6 decisions in this area. To zoom in, answer Q-color-02.
<!-- od:zoom area=color level=0 -->

**One accent color: a brown picked for you (`#b4532a`) marks buttons, links and focus.** Everything else stays neutral.
Designers: primary or brand accent · Code: `color.bg.accent`

<details><summary>More</summary>

**Your answers here** (each one either sets tokens or is a rule for this section):
- Your text, backgrounds and lines use grays. **Warm tint** (delegated; tokens; Q-color-09)

**Intent.** Brand color `#b4532a` drives the accent ramp's hue; the Colorfulness dial (38) sets its chroma (scheme tonalSpot, peak HCT chroma 52.2). The brand's role is **accent+signature-surface** and it sits closest to accent step 9. Picked for you, not chosen by you: a brown (#B4532A) on buttons, links and focus, with white text that reads clearly on it.

**How ramps are built.** Each hue gets twelve steps in OKLCH, placed by contrast. Step 8 reaches at least 3:1 (edges and focus). Steps 10 and 11 reach the text minimum on backgrounds 1-4. Step 12 reaches at least 7:1. Steps 2-6 are spaced evenly in lightness between step 1 and step 7. Light and dark ramps are solved separately. Dark solids are lighter and carry dark text (dark mode is a separate mapping, never an inversion). Text minimum: 4.5:1 (WCAG 2.2 AA).

| Ramp | Light steps 1-12 | Solid carries |
|---|---|---|
| `accent` | `#fffcfb` `#fcf2ef` `#fbe8e0` `#fbddd1` `#fbd2c2` `#fac7b3` `#f9bca4` `#bd7356` `#b4532a` `#a44923` `#8e401e` `#502a1b` | light |

**Step-distance guarantee** (neutral, light; WCAG contrast of a foreground step on background steps 1-5):

| Foreground | on 1 | on 2 | on 3 | on 4 | on 5 |
|---|---|---|---|---|---|
| neutral 8 | 3.56 | 3.32 | 3.07 | 2.83 | 2.62 |

| neutral 12 | 15.15 | 14.10 | 13.05 | 12.02 | 11.14 |

**States.** Hover is at least 1.15:1 from its fill and pressed at least 1.3:1, as shade steps (DC-L01-17). Where a color is unknown at design time, use the state opacities in `opacity.state.*`.

| `color.text.warning` | `#845d00` | `#fdcf82` | Warning text and icons; pair with an icon or label (DC-L01-15). |

**Use / avoid.**
- Use one solid accent fill per view for the primary action; spend chroma on small, meaningful elements.
- Avoid gray text on colored fills; use the matching `text.on-*` role.
- Avoid color as the only signal: pair status colors with an icon or label.
- Charts: no chart palette yet (Q-color-19). Take chart colors from the status and accent hues, and check them separately.

## Typography

> Zoom: sketch (0 of 3), 2 decisions in this area. To zoom in, answer Q-type-01.
<!-- od:zoom area=typography level=0 -->

**Body text is 16px, and each larger size is about 1.25 times the one below.**
Designers: type scale: base size and ratio · Code: `font.size.14`

<details><summary>More</summary>

**Intent.** Body text is 16px; sizes follow `round(16 x 1.25^n)` for n from -2 to 4, reaching about 2.5x body (product surfaces only). Sizes: 13, 16, 20, 25, 31, 39px.

- Text face: Instrument Sans, system-ui, -apple-system, Segoe UI, Roboto, Helvetica Neue, Arial, sans-serif. Licence status (hook H-type): **pending**.
- Licence by platform: text: Instrument Sans (open licence or system font: web, apps and self-hosting); display: Newsreader: licensed for web, apps, self-hosting.
- On iOS the Swift file uses Dynamic Type text styles (body 17 pt), so text follows the person's text size setting; Compose uses sp, which follows the Android font scale.
- Weights: body 400, label 500, heading 600 (two or three distinct weights per view).
- Emphasized variants: off (they turn on at Expression 67 and up, DC-L02-11).
- Line heights snap to a 4px grid: 1.5 up to 17px, 1.4 to 26px, 1.25 to 44px, 1.12 above.
- Letter spacing: +0.02em at 11-12px, -0.01em from 32px, -0.02em from 48px.
- Text scaling: CSS sizes are rem, line heights unitless, so text scales to 200% (WCAG 1.4.4); containers must grow with it.
- Scripts: Latin only; add scripts in raw.scripts to get per-script line heights (DC-L02-25).

| Style | Size/line (px) | Weight | Tracking | Use |
|---|---|---|---|---|
| `text.body.lg` | 20/28 | 400 | 0em | Long-form reading, onboarding copy. |
| `text.body.md` | 16/24 | 400 | 0em | Default UI text: forms, tables, descriptions. |
| `text.body.sm` | 13/20 | 400 | 0em | Helper text, timestamps, captions. |
| `text.code.md` | 16/24 | 400 | 0em | Code blocks, token names. |
| `text.code.sm` | 13/20 | 400 | 0em | Inline values, dense code rows. |
| `text.headline.md` | 39/48 | 600 | -0.01em | Page and section titles. |
| `text.headline.sm` | 31/40 | 600 | 0em | Page and section titles. |
| `text.label.lg` | 16/24 | 500 | 0em | Button and control labels. |
| `text.label.md` | 13/20 | 500 | 0em | Small control labels, badges, dense tabs. |
| `text.label.sm` | 13/20 | 500 | 0.05em caps | Overlines in capitals with wide tracking (DC-L02-18). |
| `text.title.lg` | 25/36 | 600 | 0em | Card, panel and group titles. |
| `text.title.md` | 20/28 | 600 | 0em | Card, panel and group titles. |
| `text.title.sm` | 16/24 | 600 | 0em | Table headers, field-group titles. |

**Use / avoid.**
- Use at most three sizes and two weights in one view; let color and weight carry hierarchy before size.
- Avoid all caps for sentences and in scripts without case; use weight for emphasis there.

**Tailwind classes:** `text-body-md`, `text-label-lg`, `text-title-md`, `text-headline-md`.

## Layout

> Zoom: sketch (0 of 3), 1 decision in this area. To zoom in, answer Q-space-01, Q-space-02, Q-space-03.
<!-- od:zoom area=layout level=0 -->

**Spacing comes in steps of 4px, and screens use spacious spacing by default.**
Designers: spacing scale, 0 to 96 · Code: `space.0 to space.96`

<details><summary>More</summary>

**Intent.** Everything sits on a 4px unit: ladder 0, 2, 4, 6, 8, 12, 16, 20, 24, 32, 40, 48, 64, 80, 96. Density is a mode on the semantic layer (default **spacious**). Primitives and minimum tap areas never change.

| Density | inset xs/sm/md/lg/xl | section sm/md/lg | control sm/md/lg | outer:inner |
|---|---|---|---|---|
| spacious (default) | 6 / 12 / 16 / 20 / 32 | 64 / 80 / 96 | 40 / 48 / 56 | 3.5 |
| comfortable | 4 / 8 / 12 / 16 / 24 | 32 / 40 / 64 | 32 / 40 / 48 | 2.5 |
| compact | 2 / 6 / 8 / 12 / 20 | 16 / 24 / 40 | 24 / 32 / 40 | 2.0 |

- Target sizes: pointer 24px, touch 44px; `size.target.min` is the floor for the primary input, and `space.target.gap` separates adjacent targets.
- Inner gaps stay below outer gaps (at least half), so grouping reads without borders (L15 P16).
- Breakpoints and grid: not generated yet; use the platform defaults and keep layout spacing independent of density (DC-L03-17).

**Use / avoid.**
- Parents own spacing (padding and gap); children never set outer margins.
- Avoid values off the ladder; if one is needed, add it as a decision.

## Elevation & Depth

> Zoom: sketch (0 of 3), 1 decision in this area. To zoom in, answer Q-depth-01.
<!-- od:zoom area=elevation level=0 -->

**Surfaces step in lightness; only menus and dialogs cast shadows.**
Designers: flat, shadowed, tonal or glass · Code: `$extensions.opendesigner.model`

<details><summary>More</summary>

**Intent.** Depth 45/100 selects the **tonal** model. Shadow alpha in light mode is 0.135; dark mode doubles it and lifts surfaces by lightness instead (sunken, base, raised, overlay).

| Token | Layers (x y blur spread) | Use |
|---|---|---|
| `elevation.raised` | none | Cards that lift on hover, sticky headers, dragged rows. |
| `elevation.floating` | 0 1 2 0, 0 4 12 0 | Menus, popovers, dropdowns. |
| `elevation.overlay` | 0 1 2 0, 0 12 32 0 | Dialogs and sheets (with color.overlay.scrim). |

- Borders: 1px default, 2px selected and focus, 4px emphasis; width changes use an inset shadow so layout does not jump.
- Stacking: page < raised < floating (menus) < overlay (dialogs with `color.overlay.scrim`).
- No materials or glass in this system.

Decisions: D-0016 (dials.depth).

## Shapes

> Zoom: sketch (0 of 3), 1 decision in this area. To zoom in, answer Q-shape-01.
<!-- od:zoom area=shape level=0 -->

**Buttons and fields have 12px corners; cards have 16px corners.**
Designers: corner radius, sharp to pill · Code: `radius.control, CSS border-radius`

<details><summary>More</summary>

**Intent.** Roundness 64/100 gives controls a **12** radius; details 6px, containers 16px, overlays 24px, people full. Controls under 32px tall use `radius.control-sm` (8).

- Nested radius: inner = max(outer - padding, smallest step). Here it is 2px inside a container with `space.inset.lg` padding. Equal radii on nested shapes look uneven (DC-L04-05).
- Focus ring: 2px, 2px offset, radius = control radius + offset (14).
- Icons: rounded corners, round caps. On iOS, use continuous corners (DC-L04-04).
- Signature shapes: none generated; a brand shape library is a designer asset (hook H-motif).

Decisions: D-0015 (dials.roundness).

## Components

> Zoom: sketch (0 of 3), 0 decisions in this area. To zoom in, answer Q-comp-01, Q-comp-02, Q-state-01.
<!-- od:zoom area=components level=0 -->

**Version 1 plans 27 components, all built from these tokens.**

- Does your product use AI, and if so, how should people spot and fix its work? **Chat components for products people talk to (shadcn Message, Bubble; Carbon AI chat)** (delegated; a rule here; Q-ai-01)

**Intent.** v1 components use the semantic tokens only. Base: not chosen yet (Q-comp-01). Buttons are 48px tall (spacious), 12 radius, `text.label.lg`; one primary action per view.

**Contested policies:** Validation timing and disabled submit: pending; Field style: pending; Toasts: pending; Undo versus confirm: pending; Danger actions: pending; Button emphasis levels: pending.

**Use / avoid.**
- Every interactive component shows hover, pressed, focus-visible and disabled states from the tokens.
- Inputs keep a 3:1 boundary (`color.border.input`); signifier strength: minimal-allowed.
- Component docs belong in `opendesigner/components/<name>.md` (spec 7.8).

## Do's and Don'ts

**These rules keep screens clear and easy to read.** The engine checks the ones it can.
Designers: guardrails and design linting · Code: `engine.py validate, engine.py review`

<details><summary>More</summary>

**Enforced by construction.** The generator cannot break these:
- text contrast 4.5:1, and 3:1 for edges, in every mode
- text on colored fills picked automatically
- tap areas pointer 24px, touch 44px
- a 2px focus ring with a 2px offset
- a reduced-motion mode
- inner spacing smaller than outer spacing, three text colors, and nested radii

**Do**
- Use semantic tokens; never raw hex, px or ms values in components.
- Keep one primary action per view and at most three type sizes per view.
- Pair every status color with an icon or label; underline links in running text.

**Don't**
- Don't shrink hit areas in dense layouts; shrink visuals and extend the hit area.
- Don't use motion as the only signal, or flash more than three times a second.
- Don't copy another brand's identity from a reference (colors, typeface, logo, imagery, copy).

**Current validation findings:** none (errors 0, warnings 0).

**Waivers:** none.

## Standards

**Follow these rules when you build.** They come from sources marked non-negotiable, their values are locked, and `engine.py review` checks the ones it can.

## Motion

> Zoom: sketch (0 of 3), 1 decision in this area. To zoom in, answer Q-motion-01.
<!-- od:zoom area=motion level=0 -->

**Most movements take 200ms.** They turn into fades when a person asks for less motion.
Designers: motion system: duration, easing, springs · Code: `motion.duration.*, motion.easing.*`

<details><summary>More</summary>

**Intent.** Energy 30/100: the duration multiplier x0.92 scales the extra step (standards fix medium, long). Standard easing `cubic-bezier(0.77, 0, 0.175, 1)`, enter `cubic-bezier(0.23, 1, 0.32, 1)`, exit `cubic-bezier(0.23, 1, 0.32, 1)`. Spatial spring: damping 1.0, stiffness 246.7 (Apple duration 0.4s, bounce 0.0; web `linear()` sample over 590ms).

| Token | Value | Note |
|---|---|---|
| `motion.duration.instant` | 0ms | set by house standard STD-when-to-animate-05 |
| `motion.duration.micro` | 100ms | set by house standard STD-easing-duration-07 |
| `motion.duration.short` | 150ms | set by house standard STD-easing-duration-07 |
| `motion.duration.medium` | 200ms | set by house standard STD-easing-duration-07 |
| `motion.duration.long` | 250ms | set by house standard STD-easing-duration-07 |
| `motion.duration.extra` | 640ms | illustrative and marketing motion only, never UI (STD-easing-duration-06) |
| `motion.duration.medium-exit` | 160ms | derived: about 0.8 x medium |
| `motion.duration.long-exit` | 200ms | derived: about 0.8 x long |
| `motion.duration.drawer` | 500ms | set by house standard STD-enter-exit-origin-41 |
| `motion.duration.modal` | 250ms | set by house standard STD-enter-exit-origin-11 |
| `motion.duration.reduced-fade` | 200ms | set by house standard STD-accessibility-motion-02 |
| `motion.duration.reveal` | 600ms | set by house standard STD-enter-exit-origin-26 |
| `motion.duration.stagger` | 50ms | set by house standard STD-enter-exit-origin-13 |
| `motion.duration.toast` | 400ms | set by house standard STD-components-toasts-drawers-07 |
| `motion.duration.tooltip` | 125ms | set by house standard STD-enter-exit-origin-09 |

- Exits are derived, not set on their own: each is about 20% shorter than the entrance in force (medium-exit 160ms from medium 200ms, long-exit 200ms from long 250ms; STD-easing-duration-11). Change an entrance and its exit follows. Linear easing only for spinners and progress.
- Reduced motion (`prefers-reduced-motion` or `data-motion="reduced"`): travel becomes opacity, feedback stays, `motion.transition.move` is 0ms.
- Springs are stored as damping and stiffness in `$extensions.opendesigner.spring` because DTCG 2025.10 has no spring type.
- Haptics: light intensity where the platform has them; sound: hook H-sound is pending.

## Modes and Themes

> Zoom: sketch (0 of 3), 1 decision in this area. To zoom in, answer Q-theme-03.
<!-- od:zoom area=modes level=0 -->

**The system has light and dark color modes, three spacing densities and a reduced-motion mode.**
Designers: modes: light, dark, density, motion · Code: `resolver modifiers, Figma collection modes`

<details><summary>More</summary>

**Your answers here** (each one either sets tokens or is a rule for this section):
- Should the app have light and dark modes that follow the device, or just one mode? **Light and dark, matching the device setting** (delegated; tokens; Q-theme-01)

**Intent.** Modes live in the DTCG resolver (`opendesigner/tokens/opendesigner.resolver.json`); modifiers are orthogonal, so no two set the same token.

| Modifier | Contexts | Default |
|---|---|---|
| theme | light, dark | light |
| density | spacious, comfortable, compact | spacious |
| motion | standard, reduced | standard |

- Web: `prefers-color-scheme` with a `[data-theme]` override; `[data-density]`; `prefers-reduced-motion` with `[data-motion]` (see `opendesigner/build/css/tokens.css`).
- High-contrast themes are not generated; set `raw.contrastTarget` to AAA for 7:1 text everywhere.
- A second brand or a client re-skin may override the color primitives and `color.bg.brand`; semantic names never change.

Decisions: D-0008 (answers.Q-theme-01).

## Iconography and Imagery

> Zoom: sketch (0 of 3), 0 decisions in this area. To zoom in, answer Q-icon-01, Q-icon-02, Q-icon-06.
<!-- od:zoom area=iconography level=0 -->

**Icons are 24px by default.** The logo, photos and custom icons come from a person, not from the engine.
Designers: icon system: style, sizes, color · Code: `size.icon.*, icon.stroke.*, color.icon.*`

<details><summary>More</summary>

**Intent.** Default icon size 24px; sizes 16/20/24 pair with 14/16/20px text. Stroke follows the label weight: 1.5px at 16, 2.0px at 20, 2.5px at 24. Rest style: outline.

| Asset | Hook | Status |
|---|---|---|
| Logo and marks | H-logo | pending |
| Favicon set | H-favicon | pending |
| App icon | H-appicon | pending |
| Custom icons | H-icons | pending |
| Illustration | H-illus | pending |
| Photography | H-photo | pending |
| Motifs and brand shapes | H-motif | pending |

- Placeholders are labelled as placeholders. A generated stand-in is never shown as a finished brand asset.
- Icon-only buttons need an accessible name and a hit area of `size.target.min`.

Decisions: none recorded yet; values are defaults from references/levers.json.

## Content and Voice

> Zoom: sketch (0 of 3), 0 decisions in this area. To zoom in, answer Q-voice-01, Q-voice-02, Q-voice-03.
<!-- od:zoom area=content level=0 -->

**Words stay plain and short, and every button says what it does.**
Designers: content: voice, tone, microcopy · Code: `DESIGN.md Content and Voice section`

<details><summary>More</summary>

**Intent.** Draft: voice guidance level **short** (Brand presence 62); **sentence-case**; contractions **encouraged** (Warmth 88). Voice guide hook H-voice: pending.

- Buttons say what they do in two to four words; errors say what happened and how to fix it.
- Reading level: plain language; avoid jargon in UI copy.
- Word list: not recorded yet (Q-voice-03).

Decisions: none recorded yet; values are defaults from references/levers.json.

## Accessibility

> Zoom: sketch (0 of 3), 0 decisions in this area. To zoom in, answer Q-aud-02, Q-aud-03, Q-aud-04.
<!-- od:zoom area=accessibility level=0 -->

**Text passes WCAG 2.2 AA contrast in every mode, and focus is always visible.**
Designers: WCAG 2.2 AA target · Code: `raw.contrastTarget`

<details><summary>More</summary>

**Your answers here** (each one either sets tokens or is a rule for this section):
- Who uses it, and how often: all day for work, often, or now and then on the go? **Often, in an everyday app** (delegated; tokens; Q-aud-01)

**Intent.** Standard: WCAG 2.2 AA. APCA is reported as advice only.

**The system guarantees:**
- text and edge contrast in every mode
- visible focus (2px ring, 2px offset, 3:1)
- minimum target sizes for each kind of input
- a reduced-motion mode
- rem-based type, so text scales to 200%
- text on colored fills chosen automatically

**Product teams own:** accessible names and labels, alt text, reading and focus order, and never using color alone. Also: clear error messages, dialogs that can be closed, no pre-checked consent boxes, and captions for media.

**Test on each platform:**
- keyboard only
- a screen reader (VoiceOver, NVDA or TalkBack)
- 200% zoom
- forced colors (Windows High Contrast)
- reduced motion
- touch on a phone, for every surface that allows touch

Decisions: none recorded yet; values are defaults from references/levers.json.

<!-- od:zoom area=platforms level=0 -->

**It runs on web, and each platform keeps its own navigation.**
Designers: target platforms · Code: `raw.platforms; size.target.min`

<details><summary>More</summary>

**Your answers here** (each one either sets tokens or is a rule for this section):
- Where will it run first: web, iOS, Android or desktop? **Web** (delegated; tokens; Q-plat-01)

**Intent.** Platforms: web. Inputs: pointer, touch. Brand presence 62: each platform keeps its own shapes and materials: no; each platform keeps its own body text size: no.

- Navigation, back, sheets and pickers stay native on every platform (DC-L10-02).
- Swift and Compose files in `opendesigner/build/` use the same names as the CSS variables (Figma code syntax matches them).
- Fonts by platform: text: Instrument Sans (open licence or system font: web, apps and self-hosting); display: Newsreader: licensed for web, apps, self-hosting.

## For Agents

**AI agents: read this file and the tokens before you change any screen.**

1. Before any visual work, read this file, PRODUCT.md and `opendesigner/tokens/` (start at `opendesigner/tokens/opendesigner.resolver.json`).
2. Use tokens, never raw values: CSS `var(--ds-...)`, Tailwind classes from `opendesigner/build/tailwind/theme.css`, `DS.*` in Swift, `DsTheme` in Compose.
3. Do not change a locked decision without asking the owner.
4. To change the system: `engine.py set <path> <value> --why "..."`, then `engine.py generate`, `engine.py validate`, `engine.py design-md`.
5. To extend: add a decision (never hand-edit tokens or this file). Keep semantic names the same across modes. Deprecate instead of deleting.
6. After any implementation, run `engine.py review` and re-read this file.
7. Follow the Standards section. Change a standard only when the person explicitly asks: `engine.py standard override <id> --why "<their words>"`.

**Tailwind v4 classes** (one import: `@import "tailwindcss"; @import "<path>/opendesigner/build/tailwind/theme.css";`; Tailwind's default colors, text sizes, radii and shadows are switched off, so only these exist):

| Area | Classes |
|---|---|
| Color | `bg-action-primary`, `hover:bg-action-primary-hover`, `active:bg-action-primary-pressed`, `text-on-action`, `bg-surface-base`, `bg-surface-raised`, `text-fg-primary`, `text-fg-secondary`, `text-fg-link`, `border-line-subtle`, `border-line-input`, `outline-line-focus`, `bg-danger-bold` |
| Layout | `p-inset-md`, `gap-stack-md`, `gap-inline-sm`, `h-control-md`, `size-icon-md`, `min-h-target-min` |
| Shape | `rounded-control`, `rounded-container`, `rounded-overlay`, `rounded-full` |
| Elevation | `shadow-raised`, `shadow-floating`, `shadow-overlay` |
| Type | `text-body-md`, `text-label-lg`, `text-title-md`, `text-headline-md` |
| Motion | `transition-feedback`, `ease-enter`, `ease-exit`, `ease-hover` |
