/* Cyberpunk TCG sim — shared design system.
 *
 * One file for every page the project serves: the live table (cpsim.play), the
 * step viewer (cpsim.viewer) and the tournament spectator (cpsim.spectator).
 * Pages that must stand alone (an exported replay) get it inlined by
 * `cpsim.theme.themed`; the play page links it from /static/theme.css.
 *
 * Art direction — five rules, enforced here and in every page's own CSS:
 *
 *  1. The card art is the brightest thing on screen. Surfaces are graphite in
 *     four steps; chrome never glows, and gradients stay under a few percent.
 *     A game action may light up for a moment (fx.js: a clash, sparks, a
 *     burn, since 2026-11-06); the interface around it never does.
 *  2. Colour is meaning, never decoration. Cyan is you and what you can act
 *     on; amber is the Rival and caution; red is loss and the irreversible;
 *     signal yellow means "a decision is yours" and nothing else; gold is Gigs.
 *  3. Engineered geometry. 2px corners, 1px hairlines, one chamfered corner
 *     marks a primary control. No pills except status chips, no soft blobs.
 *  4. Type carries hierarchy. Condensed capitals for labels and headings,
 *     plain sans at 14px+ for rules and choices, tabular figures for counts.
 *     Nothing animates over text; no glitch, no scanlines.
 *  5. Motion explains cause. It starts at the source and ends at the result,
 *     never loops, and has an instant equivalent (reduced motion).
