Phase 4 carries one genuine designer-side decision: dark-surface logo contrast
strategy. Recommends Option A — `currentColor` SVG + CSS color driven via the
existing `.dark, [data-theme="dark"]` block in tokens.css (lines 234-251). Post-
research amendment: welcome.ts must swap `?url` (data URL → <img>) for `?raw`
(inline <svg> via DOMParser) because <img>-rendered SVGs do not inherit parent
CSS color — `currentColor` only resolves on inline DOM SVG.
Cursor visibility constraint (Plan 01-07 obs 2026-05-15) is listed as
behavioral-only inheritance, not a design surface — 1-line change in
src/offscreen/recorder.ts per Chrome CursorCaptureConstraint enum.
Inherits Phase 1 design system as read-only (Lora display + IBM Plex Sans UI
+ Loom palette + Mokosh mark + canonical tokens.css + 17-key i18n matrix).
Zero new tokens, zero new copy, zero new colors. PNG icons unchanged.

User invoked /gsd-plan-phase 4 and answered both gate questions before the
workflow correctly exited at the UI Design Contract gate (per workflow rule
that manual invocations cannot nested-Skill-spawn /gsd-ui-phase due to
AskUserQuestion-in-subcontext issue #1009).
Preferences saved at .plan-phase-preferences.md for the next plan-phase
invocation (after /gsd-ui-phase 4 produces UI-SPEC.md):
- UI gate: generate UI-SPEC.md first — unlike Phase 3 (false positive),
Phase 4 has genuine dark-logo work; UI-SPEC should be thin-but-real
(dark-logo design only; cursor visibility listed as inherited behavioral
change, not a design surface)
- Research gate: research first (light, ~10-20 min) — scope-limited to:
setimmediate polyfill replacement strategy + SW state persistence 5min
idle test patterns + chrome.scripting.executeScript world:'ISOLATED'
best practices for A29 cs-injection-world fix. Researcher NOT to
investigate already-deferred items (rrweb v2, SW-RAM, masking).
File auto-deletes when /gsd-plan-phase 4 honors these preferences.
