/* build/tuning.css
 * ---------------------------------------------------------------
 * Blank-canvas tuning page chrome. Phase A.2a.
 *
 * Goal (per bud, 2026-05-12):
 *   - Same cyberpunk look as welcome.html, but using the new
 *     tuning-bg.png (shop / Scarecrow lift scene).
 *   - LIGHTER vignette so the image stays fully visible.
 *   - Floating ARC-TUNING wordmark at the top — no bar behind it.
 *   - Everything BELOW the header is a true blank canvas.
 *
 * No JS attached on purpose. View at:
 *   http://localhost:8787/tuning.html
 * --------------------------------------------------------------- */
