What changes

The org's branding moves to the mark and palette that commit-check.com uses in commit-check/commit-check.com#43: a commit on a history line, ticked, on an Ink (#0b1620) tile, in the same Signal Blue #2c9ccd the badge has always used.

  • Avatar, lockups, banners, favicon: redrawn. The file names are unchanged, so the profile README and anything else that links here pick up the new images without edits.
  • Social previews: social-preview.png for the org, plus one social-preview-<repo>.png per repository with its address and a panel of what it does:
    • commit-check: the CLI's CC001 output.
    • commit-check-action: the PR comment and the Action's report inputs.
    • commit-check-app: check runs.
    • commit-check-mcp: a real validate_commit_message result.
  • README badge: badge-logo.svg puts the mark in the shields.io badge. branding/README.md documents the URL.
  • Profile README:
    • Every badge takes the Ink label.
    • The Website badge carries the mark.
    • The line under the banner now matches the site.

How the images are made

Images with text are HTML pages in branding/src/, rendered by render.sh with headless Chrome. Their fonts come from Google Fonts, so re-rendering no longer needs Montserrat or anything else installed. The shape-only SVGs are rendered with rsvg-convert.

They keep v3's rule: no tagline baked into an image.

The v3 sources banner-*.svg and social-preview.svg are removed; src/*.html replaces them. logo.jpg and logo-small.jpg stay for external links, now carrying the v4 lockup.

After merge

The org avatar and each repository's social preview can only be uploaded by hand: GitHub has no API for them.

  • Avatar: Organization settings → Profile picture → branding/avatar.png.
  • Social previews: each repository's Settings → Social preview → branding/social-preview-<repo>.png.

Summary by CodeRabbit

  • Branding
    • Updated the visual identity with a new Signal mark, refreshed colors and typography, and redesigned logo and banner assets.
    • Added light and dark variants for the logo and banner, plus social preview cards tailored to individual repositories.
  • Website
    • Updated the profile tagline and website badge to match the refreshed branding.

The swoosh check gives way to the mark commit-check.com now uses: a commit
on a history line, ticked, on an Ink tile, in the same Signal Blue. The
avatar, the lockups, the README banners and the social previews are
redrawn to match, and every repository gets its own social preview with
its address and a panel of what it does.

Images with text are now HTML sources in branding/src, rendered with
headless Chrome and Google Fonts by render.sh, so re-rendering no longer
needs a font installed. They still carry no tagline.

The profile README's badges take the Ink label, the Website badge carries
the mark, and the line under the banner matches the site.

📝 Walkthrough

Walkthrough

The branding sources and guidance now use the Signal identity. New HTML pages define logo, banner, and social preview assets, and a script renders PNGs from HTML and SVG sources. The profile README updates its tagline and badges.

Changes

Signal branding and asset generation

Layer / File(s) Summary
Signal identity and base assets
branding/README.md, branding/src/brand.css, branding/src/mark.js, branding/src/logo.html, branding/src/banner.html
The guide and shared styles define Signal colors and fonts. The logo and banner pages provide light and dark variants, and the banner lists four checks.
Repository-specific social previews
branding/src/social.html
The page selects one of five preview panels using the repo query parameter and shows the organization-wide panel when the parameter is absent or unknown.
Asset rendering and profile integration
branding/src/render.sh, branding/README.md, profile/README.md
The script renders PNGs from HTML and SVG sources. The branding guide documents rendering and the badge data URI. The profile README updates its tagline and badge styling.

Asset regeneration needs a Chrome override on Linux and an undocumented dependency; unusual preview URLs may display incorrectly. These are bounded issues that can be fixed or accepted before merging.

The images with text are HTML pages in `src/`, rendered with headless Chrome;
their fonts come from Google Fonts, so nothing has to be installed. The

Document ImageMagick as a rendering requirement.

The re-rendering instructions name Chrome and rsvg-convert, but branding/src/render.sh also runs magick for both lockups. A reader who installs only the listed tools will stop at the first lockup. Add ImageMagick to this prerequisite list.

Resolve Chrome outside macOS.

On Linux, an installed Chrome executable does not exist at the macOS-only default path. The first shot then fails after the script has already replaced the shape PNGs. Resolve Chrome from PATH when CHROME is unset, while retaining the macOS fallback.

Resolve repo against the known panels before displaying a caption.

If repo contains a quote, querySelector throws before the fallback panel appears. If repo is an unknown valid name, the fallback panel appears with a caption for that unknown repository. Compare repo with the panels’ data-repo values, then build the caption from the selected panel.

Proposed fix
-  var panel = document.querySelector('[data-repo="' + repo + '"]') || document.querySelector('[data-repo=""]');
+  var panels = Array.from(document.querySelectorAll("[data-repo]"));
+  var panel = panels.find(candidate => candidate.dataset.repo === repo) || panels[0];
   panel.style.display = "block";
-  document.getElementById("repo").textContent = repo && repo !== "commit-check.com" ? "github.com/commit-check/" + repo : "";
+  document.getElementById("repo").textContent = panel.dataset.repo
+    ? "github.com/commit-check/" + panel.dataset.repo : "";

The badge keeps its Signal Blue #2c9ccd, takes an Ink label, and carries
the Commit Check mark in place of the generic Git logo, matching
commit-check.com and the org branding (commit-check/.github#61). It now
links to commit-check.com, where a reader who wonders what the badge
means finds out.
