/* The Infinite Archive — design-language CSS
 *
 * Tokens, reset, base typography, scanline overlay, and shared header /
 * logo / nav chrome. Loaded by every page; page-specific styles continue
 * to live in each page's <style> block until Phase 1 step 3 moves them
 * out into per-page CSS or templates.
 *
 * Phase 1 step 1: extracted from the duplicated inline <style> blocks in
 * the seven v0 pages. Canonical values are the majority across those
 * pages; the two divergent rules (html/body line-height on index,
 * awakenings, strength-index; .logo-text font-size on quantum) are kept
 * as one-line overrides in those pages' inline <style> blocks so v0
 * rendering is preserved exactly.
