Summary

Replace the Kanye image on unofficial-result charts with a generated pointing
Muse mascot matching the supplied pose reference: left-pointing hand, tilted
head, open-mouth expression, and a transparent full-body silhouette.

• Use a 768 × 768 transparent WebP (109 KB) and remove the old PNG.
• Preserve watermark opacity, plot-area sizing, warning text, layer order,
  pointer-event behavior, and removal when the last unofficial run is dismissed.
• Keep official-result charts and the existing Muse model icon unchanged.
• Update the unit/E2E asset assertions and document image provenance. The
  generated illustration is not official Meta/Muse artwork.

Screenshots

These are actual local app screenshots with E2E_FIXTURES=1 and the repository's
muse-spark-unofficial-run.json fixture. The single B200 point is fixture data,
not a new live benchmark measurement. Screenshot files live on a separate
evidence branch and are not part of this application diff.

AI model disclosure

• GPT-6 Astra Ultrafast (session runtime label): implementation, tests, browser
  QA, and PR preparation. No delegated agents.
• GPT Image 2.5 Flare (gpt_image_2_5_flare): generated the transparent pointing
  mascot from the supplied pose screenshot and a texture/color reference.

Validation

• Focused Vitest suites: 51/51 passed (watermark.test.ts, chart-setup.test.ts).

• Cypress unofficial-watermark.cy.ts: 1/1 passed with the final pointing asset.

• Cypress chart-button/scatter-graph component suites: 60/60 passed.

• Playwright: light/dark desktop and 375 px mobile screenshots; no horizontal
  mobile overflow; PNG export contains the pointing mascot.

• Official DeepSeek R1 fixture: 153 visible plot shapes and no unofficial
  watermark. Dismissing the unofficial run also removes the watermark.

• TypeScript, lint, formatting, typography, and git diff --check: passed.

• Full app unit suite under Node 24.22.0: 463 files passed, 9,726 tests passed,
  four skipped. Constants package: all 63 tests passed. Database package:
  all 1,122 tests passed.

• Environment note: the sandbox default Node 20.20.2 is incompatible with the
  installed JSDOM runtime. The successful app run used Node 24.22.0.

• GitHub: all 32 active checks passed, including Chrome/Firefox E2E shards,
  component shards, typecheck/unit tests, lint, CodeQL, and Vercel. Four
  conditional checks were skipped.

• Local production build not run; Vercel preview build passed. No routing,
  server, dependency, or data changes.

• I have completed the AI model disclosure and kept it current.
