# Isobath

**Isobath** 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:** landing page (a page that shows off and invites people in)

- **Runs on:** web

- **Feel:** calm, technical (deferential, minimal, modern, serious; picked for you)

- - **Brand color:** Picked for you, not chosen by you: a teal (#008194) on buttons, links and focus, with white text that reads clearly on it.

+ - **Brand color:** Picked for you, not chosen by you: a teal (#008194) on links, selection and focus. In dark mode, brand fills use a lighter shade of it (#2290A3), so their dark text reads clearly. Buttons use your primary action color (#3FC1D9).

- **Decided:** 7 picked for you; everything else uses sourced defaults

- **Standards:** 288 house standards followed (locked, house standards v2), 1 overridden by you; 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 `` blocks survive). Each section opens with one plain sentence; open **More** for the designer and engineer detail.

## Overview

> Zoom: broad (1 of 3), 7 decisions in this area. To zoom in, answer Q-scope-02, Q-scope-05, Q-brand-02.

**Isobath feels deferential, minimal, modern and serious. Screens are roomy, in a flat style.**

Designers: visual style: flat, tonal, glass · Code: `preset in state.json`

**Your answers here** (each one either sets tokens or is a rule for this section):

- How much should fit on a screen: compact, comfortable, or spacious? **Spacious** (delegated; tokens; Q-dir-02)

- What are these screens mostly for: selling, getting work done, reading, or enjoying an experience? **landing page (Persuade)** (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: landing page (Persuade: density spacious; one hero line per page; sections, not card grids)

- Platforms: web; inputs: pointer, touch

- Direction: preset flat2 (the default until Q-dir-01 is answered); feel deferential, minimal, modern, serious (words picked for you: calm, technical)

**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 45/100** (productive to expressive: balanced): type ratio 1.25, hero moments: significant-moments, expressive motion: significant-moments, brand color role: accent+signature-surface, containment: mixed.

- **Brand presence 35/100** (native to brand-led: leaning native): typeface suggestion: open-neutral-face, brand color placement: accent+signature-surface, native component share about 86%, voice guidance: none.

- **Density 20/100** (spacious to compact: spacious): body 16px on the web, default control 48px, density mode spacious, icons 24px; hit areas never shrink.

- **Energy 20/100** (calm to energetic: calm): standard easing [0.77, 0, 0.175, 1], duration multiplier 0.88, spring damping 1.0, heading weight 600, navigation: recessive.

- **Roundness 0/100** (sharp to soft: sharp): control radius 0, icon corners sharp, caps square.

- **Depth 10/100** (flat to deep: flat): depth model: borders.

- **Colorfulness 30/100** (monochrome to vivid: monochrome): scheme neutral, accent chroma 40.1 (HCT), 1 accent(s), surfaces: neutral+one-accent.

- **Warmth 10/100** (cool/formal to warm/friendly: cool/formal): neutral tint chroma 0.038 at hue 257, borders: strong-rules, title-case, contractions none.

**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.

- **One accent color: a teal picked for you (`#008194`) marks buttons, links and focus.** Everything else stays neutral.

+ **Buttons use your primary action color `#3FC1D9`; your brand color `#008194` marks links, selection and focus.** Everything else stays neutral.

Designers: primary or brand accent · Code: `color.bg.accent`

- **Intent.** Brand color `#008194` drives the accent ramp's hue; the Colorfulness dial (30) sets its chroma (scheme neutral, peak HCT chroma 40.06). The brand's role is **accent+signature-surface** and it sits closest to accent step 9. Picked for you, not chosen by you: a teal (#008194) on buttons, links and focus, with white text that reads clearly on it.

+ **Intent.** Brand color `#008194` drives the accent ramp's hue; the Colorfulness dial (30) sets its chroma (scheme neutral, peak HCT chroma 40.06). The brand's role is **accent+signature-surface** and it sits closest to accent step 9. Picked for you, not chosen by you: a teal (#008194) on links, selection and focus. In dark mode, brand fills use #2290A3, a lighter shade of it, because the dark text on dark-mode brand fills would read at only 3.98:1 on the exact color. Buttons use your primary action color (#3FC1D9).

**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).

**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 | 3.30 | 3.07 | 2.82 | 2.61 |

| neutral 12 | 15.24 | 14.13 | 13.11 | 12.08 | 11.15 |

**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.tertiary` | `#506681` | `#8097b4` | Captions and placeholders (still meets the text minimum on surfaces 1-4). |

**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.

**Tailwind classes:** `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`.

## Typography

> Zoom: sketch (0 of 3), 3 decisions in this area. To zoom in, answer Q-type-01.

**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`

**Intent.** Body text is 16px; sizes follow `round(16 x 1.25^n)` for n from -2 to 8, reaching about 5.5x body (marketing surfaces in scope). Sizes: 13, 16, 20, 25, 39, 49, 76, 95px.

- Text face: IBM Plex Sans, system-ui, -apple-system, Segoe UI, Roboto, Helvetica Neue, Arial, sans-serif. Licence status (hook H-type): **pending**.

- Licence by platform: text: IBM Plex Sans (open licence or system font: web, apps and 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).

|---|---|---|---|---|

| `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.display.lg` | 95/108 | 600 | -0.02em | One hero line per page: marketing, empty states. |

| `text.display.md` | 76/84 | 600 | -0.02em | One hero line per page: marketing, empty states. |

| `text.headline.lg` | 49/56 | 600 | -0.02em | Page and section titles. |

| `text.headline.sm` | 39/48 | 600 | -0.01em | 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.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`.

## Layout

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

**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`

**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.

- |---|---|---|---|---|

- | 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 |

+ |---|---|---|---|---|---|

+ | spacious (default) | 6 / 12 / 16 / 20 / 32 | 64 / 80 / 96 | 40 / 48 / 56 | 52 / 56 / 64 / 80 | 3.5 |

+ | comfortable | 4 / 8 / 12 / 16 / 24 | 32 / 40 / 64 | 32 / 40 / 48 | 44 / 48 / 56 / 72 | 2.5 |

+ | compact | 2 / 6 / 8 / 12 / 20 | 16 / 24 / 40 | 24 / 32 / 40 | 36 / 40 / 48 / 64 | 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.

Decisions: D-0022 (dials.density).

## Elevation & Depth

> Zoom: sketch (0 of 3), 1 decision in this area. To zoom in, answer Q-depth-01.

**Surfaces are separated by thin borders, with no shadows.**

Designers: flat, shadowed, tonal or glass · Code: `$extensions.opendesigner.model`

**Intent.** Depth 10/100 selects the **borders** model. Shadow alpha in light mode is 0.0; 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` | none | Menus, popovers, dropdowns. |

| `elevation.overlay` | none | 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-0019 (dials.depth).

## Shapes

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

**Buttons and fields have 0px corners; cards have 0px corners.**

Designers: corner radius, sharp to pill · Code: `radius.control, CSS border-radius`

**Intent.** Roundness 0/100 gives controls a **0** radius; details 0px, containers 0px, overlays 0px, people full. Controls under 32px tall use `radius.control-sm` (0).

- Nested radius: inner = max(outer - padding, smallest step). Here it is 0px 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 (0).

- Icons: sharp corners, square 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-0018 (dials.roundness).

## 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`

**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:** warn: light: color.bg.action.primary (#36c2db) on color.surface.base (#fbfdff) is 2.08:1, needs 3.0:1, warn: light: color.bg.action.primary (#36c2db) on color.surface.raised (#ffffff) is 2.12:1, needs 3.0:1

+ **Current validation findings:** warn: light: color.bg.action.primary (#3fc1d9) on color.surface.base (#fbfdff) is 2.09:1, needs 3.0:1, warn: light: color.bg.action.primary (#3fc1d9) on color.surface.raised (#ffffff) is 2.13:1, needs 3.0:1

**Waivers:** none.

## Motion

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

**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.*`

**Intent.** Energy 20/100: the duration multiplier x0.88 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` | 620ms | 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.

**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`

**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? **Dark only** (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 | dark |

| 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-0012 (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.

**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.*`

**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.

**Words stay plain and short, and every button says what it does.**

Designers: content: voice, tone, microcopy · Code: `DESIGN.md Content and Voice section`

**Intent.** Draft: voice guidance level **none** (Brand presence 35); **title-case**; contractions **none** (Warmth 10). 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.

**Text passes WCAG 2.2 AA contrast in every mode, and focus is always visible.**

Designers: WCAG 2.2 AA target · Code: `raw.contrastTarget`

**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.

## Platforms and Devices

> Zoom: sketch (0 of 3), 1 decision in this area. To zoom in, answer Q-plat-05, Q-plat-10, Q-plat-08.

**It runs on web, and each platform keeps its own navigation.**

Designers: target platforms · Code: `raw.platforms; size.target.min`

**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 35: each platform keeps its own shapes and materials: yes; each platform keeps its own body text size: yes.

- 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: IBM Plex Sans (open licence or system font: web, apps and 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.

+ 2. Use tokens, never raw values: CSS `var(--ds-...)`, Tailwind classes from `opendesigner/build/tailwind/theme.css`, `DS.*` in Swift. In Compose: colors from `LocalDsColors.current` (provide `DsLightColors` or `DsDarkColors`), then `DsSpace`, `DsType` and `DsMotion`.

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 |

| 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` |

| Motion | `transition-feedback`, `ease-enter`, `ease-exit`, `ease-hover` |
