 * Reset — SAFE global subset
 * ----------------------------------------------------------------------------
 * Loaded globally on every page via <link>. MUST NOT break existing layouts.
 * Only contains rules that are either:
 *   - already present in every page's inline styles (box-sizing, body margin)
 *   - pure additive (utility classes, :focus-visible refinements)
 *   - cascade-safe with reduced-motion
 *
 * The FULL reset (h1 margins, button resets, input styling, ul padding, link
 * colors, etc.) lives in /styles/reset-full.css and is loaded by shared
 * layouts in sub-phase 4A.2.
