[zJay26]

Claude Usage now shares the Codex Usage brand layout, using the selected A terracotta palette on the unchanged D8 geometry. The dashboard gains a clearer icon and plain by zJay signature; both README titles stay independently centered with a small, unlinked signature at the lower-right.

• Reorganizes both READMEs around download, installation and opening the dashboard, preserving Claude-specific accounting, cache, Thinking and task-tree documentation.
• Shares one SVG across the dashboard, favicon, touch icon, README and media pipelines; adds content-versioned icon URLs and Pages subpath support.
• Refreshes synthetic screenshots, both walkthrough GIFs/MP4s, social cover, posters and all four promo cuts. The 64.4-second promo timeline, music and 14-chapter walkthrough interactions are retained.

Validation: Go tests, vet and Windows build; all 28 Playwright tests; 12 language/theme/viewport checks; actual GitHub README rendering at 1440, 390 and 320px in both languages (center offset 0, right gap 0, signature 13.5px, no links or visible overlap). Icon exports match the selected candidate. All eight videos/GIFs decode without errors; promo cuts retain 1932 frames at 30fps with AAC audio. Evidence is recorded in docs/branding/validation.json and docs/branding/media-validation.json.

No accounting, database, history or public API changes. No release tag or installed service upgrade.
