feat(brand): Mono Ink identity — Vee-eye icon + scan animation, default theme, voice

[New1Direction]

Summary

Carries the approved brand-identity spec into the extension: a cool Mono Ink palette, the single Vee-lens icon, an animated scanning icon, Mono Ink as the default theme, a wordmark + new tagline, and a warmer, de-slopped Vee voice. Fully client-side; extension-only (no website changes, so no Pages deploy).

Spec: docs/superpowers/specs/2026-06-16-brand-identity-design.md · Plan: docs/superpowers/plans/2026-06-16-brand-identity.md.

What's in it (4 phases, 17 tasks)

• Icon system — icon-draw.js (shared canvas drawer, unit-tested), real Mono Ink PNGs (16/32/48/128) replacing the stubs + manifest wiring, icon-anim.js scan animation (aperture grow → spin, ring breathes grey→blue) hooked into background.js runAnalysis (always-stops on success/error, no-ops without a tabId), animateIcon setting + persisted reduceMotion gating.
• Theme — [data-theme="monoink"] full token block, made the engine default (theme.js, theme.test.js updated); Vee glyph recolors via tokens; cobalt-on-white passes AA.
• Wordmark + tagline — assets/wordmark.svg lockup; tagline → "Click any repo. Get a straight answer on whether to use it." (emoji dropped).
• Voice — vendored stop-slop under docs/style/, re-voiced onboarding-copy.js (warm, human), README/CHANGELOG de-slop.

Reviews

• Voice review: ship-ready (applied the recommended cuts).
• Whole-branch review: found + fixed a CRITICAL (options.html smart-quotes that crashed the options page) and a LOW; everything else clean.

Test plan

• 843 tests / 86 files green; eslint . 0 errors; node --check on all touched JS
• Icon PNGs render correctly (verified the 128px via canvas render)
• Load unpacked: toolbar icon is the dark-tile Vee eye; it animates during a scan and resets after
• Fresh profile defaults to Mono Ink; the other 13 themes still switch; Options → Interface toggles (mascot + animate-icon) work
• Reduced-motion / animateIcon off ⇒ static icon
