docs: Typography v1 + Foundation Colors + Anti-Patterns
- LANDVEX_DESIGN_SPECIFICATION.md:
- Typography v1 (chapter 3): Inter + JetBrains Mono, type scale,
heading hierarchy, line height rules, letter spacing, max line length,
tabular figures, numerical typography
- Foundation Colors (chapter 4.1): 12-step neutral palette (neutral-0 to neutral-1000)
- Semantic Colors (chapter 4.2): surface, text, border mappings
- Brand Palette (chapter 4.3): placeholder for brand colors
- Semantic Status Colors (chapter 4.4): green, yellow, red, blue
- Map Layer Palette (chapter 4.6): dedicated geospatial palette
- Updated primitive references from gray-* to neutral-*
- DESIGN_ANTI_PATTERNS.md (v1.0, LOCKED):
- 19 anti-patterns across 5 categories: visual, technical, interaction,
content, AI-specific
- Each with: forbidden description, rationale, alternative
- AI-specific rules: no hardcoded values, no invented components,
no skipping token lifecycle
Rationale: Typography before colors (harder to change). Neutral palette
before brand (90% of surface area). Anti-patterns prevent recurring
mistakes and guide AI agents.
