Description

Adopts the selected Heph accent + signal blue identity wherever the hammer represented the Hephaestus product. The solid mark now identifies the product; the bare, animated Heph remains the mentor persona.

This change:

  • applies the shared mark and wordmark to the app header, sign-in flow, About page, README, documentation, maintenance page, favicons, installed-app icons, and link previews;
  • establishes webapp/brand/hephaestus-mark.svg as the static source and generates every tracked brand and README asset through one deterministic exporter;
  • adds a CI freshness check so generated brand assets cannot drift;
  • gives unlabeled mentor icons decorative semantics and verifies labeled/unlabeled behavior in Storybook; and
  • removes obsolete hammer artwork, duplicate static marks, old favicons, and the unused agile_hephaestus.png.

The contributor brand asset guide records the source, generation command, usage matrix, and external-account follow-up without duplicating implementation rationale.

Review in Storybook

Open the published Storybook for this PR.

Review:

  • components → brand → Hephaestus Logo — lockup, light/dark modes, mark scale, platform crops, and wordmark;
  • components → brand → Heph Icon — default, streaming, static, and labeled mentor states.

docs/static/img/brand/external-app-icon-1024.png, slack-app-icon-512.png, and github-repository-social-preview-1280x640.png are ready for their GitHub and Slack settings. Maintainers must upload them after merge because those account settings are outside repository control. The organization profile repository already uses the new lockups and carries org-avatar-1024.png; GitHub still requires an organization owner to upload that avatar through organization settings.

How to test

  1. Run pnpm --filter webapp run storybook:dev and inspect both brand story groups in light and dark modes.
  2. Check the app header, sign-in card, About page, and maintenance page at mobile and desktop widths.
  3. Check the README and documentation navbar in light and dark modes.
  4. Run pnpm --filter webapp run export:assets && git diff --exit-code to verify the single exporter reproduces every tracked brand and README asset.

Local verification:

  • pnpm run format
  • pnpm run check
  • pnpm --filter webapp run test:storybook — 1,616 passed
  • pnpm --filter webapp run build-storybook
  • pnpm --filter docs run build
  • repeated asset generation with byte-identical output, using a pinned font

Checklist

  • My changeset summary reads as an operator/user-facing note (it becomes the changelog entry) — see .changeset/README.md
  • No operator action is required; the separate GitHub App upload is identified as a maintainer follow-up
  • I did not commit generated-artifact changes that this PR did not cause

Screenshots

The published Storybook is the review artifact for responsive scale, color modes, and mentor animation.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 48977

This PR changes shared branding and generated assets across the application, documentation, and previews. The current head still carries a lint failure, a possible overflowing social-card mark, and a dependency range that can make generated assets drift over time; these bounded issues should be fixed or explicitly accepted before merging.

Configure Stylelint for the CSS Modules selector.

Stylelint reports :global as an unknown pseudo-class on Line 31. This prevents a clean style lint run. Configure selector-pseudo-class-no-unknown to allow global, while retaining the CSS Modules selector.

Pin the font package version used by the exporter.

@fontsource-variable/inter uses ^5.3.0, which permits later 5.x releases during a lockfile refresh. The exporter embeds this package's font file in generated PNGs, so changed font metrics can change the output. Use exact version 5.3.0.
