/* Night Hearth — semantic alias layer + base atmosphere.
 * HAND-MAINTAINED. Loads AFTER css/night-hearth-tokens.css (the generated
 * file — NOT the legacy Deep Signal css/tokens.css) and maps
 * scale stops to meaning. Pages use --nh-* names, never raw --color-* stops,
 * so the underlying scales can be regenerated without touching page CSS.
 * Truth doc: DESIGN.md. Direction: redesign/DESIGN-DIRECTION.md.
