# Task
Add Shipseal to this repository so publishing a GitHub release automatically generates and
attaches social images.

# Context
Shipseal is an open source CLI and composite GitHub Action.
Docs: https://shipseal.dev  Machine readable: https://shipseal.dev/llms.txt
Package: shipseal on npm, Node 22+, MIT. Renders with Takumi, no browser and no image model.

# Steps
1. Run `npx shipseal@latest init --yes` at the repository root. It detects the brand
   (name, tagline, colours, logo, fonts) and writes .shipseal/brand.json and
   .shipseal/config.json. Commit both.
2. Open .shipseal/brand.json and check the colours. Any colour it could not detect is
   reported as a built-in default in the init output, so fix those by hand.
3. Add .github/workflows/shipseal.yml:

   name: Shipseal
   on:
     release:
       types: [published]
   permissions:
     contents: write
   jobs:
     visuals:
       runs-on: ubuntu-latest
       steps:
         - uses: actions/checkout@v4
           with:
             fetch-depth: 0
         - uses: akii09/shipseal@v0.0.6
           env:
             GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

4. Add .shipseal/output/ to .gitignore.
5. Verify locally with `npx shipseal@latest release --dry-run`, which prints the facts it
   collected without rendering anything.

# Constraints
- fetch-depth: 0 is required. Without full history and tags the release facts are incomplete.
- Do not invent values in brand.json. If a colour is not found in the project, leave the
  default in place and tell me which ones need my attention.
- Do not add an image generation dependency, and do not add a headless browser. Shipseal is
  deterministic on purpose.
- Do not edit files under .shipseal/output. They are generated.

# Done when
- .shipseal/brand.json and .shipseal/config.json exist and are committed.
- The workflow file exists with fetch-depth: 0 and contents: write.
- `npx shipseal@latest release --dry-run` prints facts with no error.
- You have told me every colour that fell back to a built-in default.

# Task
A Shipseal card came out wrong. Diagnose it from evidence, not from guesses.

# Gather evidence first, change nothing yet
1. Run `npx shipseal@latest doctor`. It checks Node, git, a shallow clone, brand.json,
   fonts, the logo and the renderer.
2. Run `npx shipseal@latest release --dry-run --json`. This prints every collected fact
   with its provenance and renders nothing.
3. Read .shipseal/output/<tag>/manifest.json. Every file, fact, computed value, warning and
   missing fact is listed there.

Read these before changing anything:
- A wrong number is a source problem, never a template problem. Find the fact in the
  manifest and check its `ref`.
- A "fit-warning" means text was shrunk or truncated. Shorten the copy rather than widening
  the template.
- A missing element is listed under `missing` with the fact that caused it.
- Wrong colours mean detection failed. The init output names every colour that fell back to
  a built-in default.
