Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# DESIGN.md

The look of the website (`site/`, `just site`), in rules. It follows the manner of the author's
sister sites, h0ffmann/closed-source and h0ffmann/ww3-gpu, with its own palette.

## One sentence

Uma folha, a caneta de quem escreve e a caneta da revisão.

## The two pens

Each pen means one thing, everywhere on the page. Words always back up the colour: a reader who
does not see colour loses nothing.

| Pen | Hex | It means |
|---|---|---|
| `--pen` | `#1D3FD0` | the writer: the title, the links, the main button |
| `--review` | `#C8102E` | the correction: a rule's id (`PTW-1`), a level of rigor |

No third pen. A new colour is a new meaning, and it starts here.

## The ground

Light only, like paper: `--paper #FBF8F1` behind everything, `--sheet #FFFFFF` under code,
`--rule #E4DDCD` for the lines between sections, `--ink #1B1A17` for the text and
`--muted #6B665C` for what is secondary.

## Type

- Fraunces (800 and 600) for the title and the headings.
- Source Serif 4 for the prose.
- JetBrains Mono for data: rule ids, levels, commands, the navigation.

The fonts load from Google Fonts, as on the sister sites. No font file is stored here.

## Shape and words

How to install

The exact contents, by fingerprint
mdr add h0ffmann/ptbr-writer/DESIGN.md@sha256:3d0b74622f262573

The line at the top of this page pins the label git:20261030.4367434, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
