/* v2.css — Direction-A look (design_v2), P0 Foundation.
 *
 * SCOPE: every rule is prefixed with [data-design="v2"] (shell.js stamps this on
 * <html> only for a flagged shop). With the flag OFF the attribute is absent, so NONE
 * of this applies and the app renders v1 byte-for-byte. Rollback = flag off, no deploy.
 *
 * P0 is FOUNDATION ONLY: design tokens + the left hub rail (≥1024px) + the hub tab
 * strip. No per-screen component restyles (those are P1–P3), no markup/id/handler
 * changes, and print / thermal / PNG / WhatsApp output CSS is untouched (locked).
 *
 * Tokens (DESIGN_WAVE_PLAN §6): Inter · ground #f4f5f1 · surface #fff · ink #121412 ·
 * green #0f6b43 (single accent) · red #b42318 · amber #9a5b00 on #fff1e2 · chips
 * #e6f2ec / #eef0ea · radius 18/22 cards, 12 inputs · tabular numerals on money.
 */

/* ---------- 1. Tokens: re-point the base CSS variables ----------
   The whole app reads var(--bg)/var(--ink)/var(--brand)/… so swapping the tokens here
   re-skins surfaces at the foundation level without touching any component rule. v2 is
   a light look; it intentionally overrides dark tokens too (loads after base.css). */
