/* ─── Intersect — style.css (Production v2.0) ──────────────────────────────
 *
 * Changes from v1:
 *  - user-select: none removed from * (was blocking form inputs despite override)
 *  - touch-action: manipulation removed from * (was suppressing pinch-zoom)
 *  - Both properties applied only to draggable word pills and non-text elements
 *  - prefers-reduced-motion: animations disabled/minimized
 *  - prefers-color-scheme: dark already default (base is dark-first)
 *  - CLS prevention: min-height locks on zone-content containers
 *  - WCAG 2.1 AA contrast: all text on var(--surface) passes 4.5:1
 *  - will-change applied only on active drag state (not statically)
 *  - Hidden elements use [hidden] attribute selector instead of .hidden class
 *    (JS toggles the 'hidden' attribute)
