/**
 * Peak AI Design — Unified node detail styles (refined v2 2026-05-07)
 * Used by article + page + portfolio (full view mode).
 *
 * Design principles applied:
 *   1. Modular type scale (1.25 "major third" ratio)
 *   2. Vertical rhythm — line-height 1.7 body, predictable margin scale
 *   3. Optimal line length — body text capped at 70ch (readability research)
 *   4. Tailwind Typography "prose" defaults adapted for Peak AI Design
 *   5. Existing theme variables (--peak-font-body, --peak-font-heading) honored
