v0.7.4 -- Build pipeline quality fixes

Token-Mapping Bug Fixed

The foundations agent was supposed to convert .yml hex tokens to shadcn HSL CSS variables but had no mapping spec — it guessed the conversion and produced incomplete output. token-mapping.md (which defines all 26+ shadcn CSS variables, hex→HSL conversion, and dark mode mapping) is now explicitly passed to the agent and referenced in its instructions.

If your previous builds had missing CSS variables or incorrect color values in globals.css, this is the fix.

Scaffold Context Capture

A new Step 5.5 runs npx shadcn@latest info --json during scaffold and captures the project context — aliases, tailwindVersion, resolvedPaths, isRSC, and more. The foundations agent now knows the actual project configuration instead of inferring it.

Shadcn Composition Rules

The builder methodology now includes the critical shadcn/ui composition rules that were missing:

• Use semantic tokens (bg-primary, text-primary-foreground) — never raw color values
• Use gap-* for spacing in flex/grid — not space-y-*
• Card composition: always wrap with CardHeader, CardContent, CardFooter
• Icons: use data-icon attribute, never hardcode sizes
• CLI awareness: run npx shadcn@latest add before customizing, use --dry-run for updates

Brand Fidelity Gates in Design

The low-quality preview.html wireframe deliverable has been removed — it was generating system-font HTML that set wrong expectations and wasted 30-90s of agent time per run.

In its place: a new Step 0 "Internalize brand DNA" forces the designer to extract all style constraints, patterns, effects, and bold bets before drawing a single screen. A Step 9 "Brand fidelity self-check" then verifies every bold bet appears in the output and no generic treatments snuck in.
