Generates a self-contained HTML page showing all prior design explorations
for a project: every variant (approved or not), feedback notes, organized
by date (newest first). Images embedded as base64. Handles corrupted
approved.json gracefully (skips, still shows the session). Empty state
shows "No history yet" with /design-shotgun prompt.

The comparison board feedback loop was fundamentally broken: browse blocks
file:// URLs (url-validation.ts:71), so $B goto file://board.html always
fails. The fallback open + $B eval polls a different browser instance.
$D serve fixes this by serving the board over HTTP on localhost. The server
is stateful: stays alive across regeneration rounds, exposes /api/progress
for the board to poll, and accepts /api/reload from the agent to swap in
new board HTML. Stdout carries feedback JSON only; stderr carries telemetry.

New `$D extract` command: sends approved mockup to GPT-4o vision,
extracts color palette, typography, spacing, and layout patterns,
writes/updates DESIGN.md with an "Extracted Design Language" section.
Progressive constraint: if DESIGN.md exists, future mockup briefs
include it as style context. If no DESIGN.md, explorations run wide.
readDesignConstraints() reads existing DESIGN.md for brief construction.

Stateless CLI (design/dist/design) wrapping OpenAI Responses API for
UI mockup generation. Three working commands:
- generate: brief -> PNG mockup via gpt-4o + image_generation tool
- check: vision-based quality gate via GPT-4o (text readability, layout
completeness, visual coherence)
- compare: generates self-contained HTML comparison board with star
ratings, radio Pick, per-variant feedback, regenerate controls,
and Submit button that writes structured JSON for agent polling
Auth reads from ~/.gstack/openai.json (0600), falls back to
OPENAI_API_KEY env var. Compiled separately from browse binary
(openai added to devDependencies, not runtime deps).
