📝 Walkthrough

Walkthrough

Storybook now serves SB Sans Display 0.3.0 fonts. Two temporary stories compare font metrics and landing-page typography. A Chromium script supports WebView-like font rasterization.

Changes

Font comparison tooling

Layer / File(s) Summary
Font assets and Storybook serving
packages/plasma-homeds/.storybook/main.ts, packages/plasma-homeds/fonts/SBSansDisplay.0.3.0/*
Added CDN and local @font-face declarations for six SB Sans Display 0.3.0 weights. Storybook serves the local font directory at /fonts.
Font metrics reproduction
packages/plasma-homeds/src/components/Typography/FontMetrics.tmp.stories.tsx, packages/plasma-homeds/src/components/Typography/open-webview-emu.tmp.sh
Added a Storybook comparison of three font families with 1× and 2× rendering views. Added a Chromium launcher with WebView-like rasterization flags.
Landing typography comparison
packages/plasma-homeds/src/components/Typography/LandingLabel.tmp.stories.tsx
Added a landing-page clone, side-by-side font comparison, and pixel-diff views using ghost, difference, and flicker overlays.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to ca6c3

The change adds font assets and typography examples; an accompanying helper script may not open the intended example because its target identifier does not match the story title. The PR is otherwise mergeable with explicit owner follow-up on that script.

Fix the default Storybook story ID.

Use 1-tmp-sb-sans-display-metrics--reproduce in open-webview-emu.tmp.sh; the story title is 1.TMP/SB Sans Display metrics and the export is Reproduce.
