/* AR-Puzzle Player polish.
 *
 * Inherits from ThinkLab brand surface:
 *   --tl-navy / --tl-navy-light / --tl-navy-dark  (background tiers)
 *   --tl-orange / --tl-orange-hover / --tl-orange-light (accent)
 *   --tl-white / --tl-gray-100 / --tl-gray-200    (text / surfaces)
 *   --tl-transition                                (default ease)
 *   --tl-primary / --tl-secondary                  (tenant-overridden hooks)
 *
 * Button classes .tl-btn / .tl-btn-primary / .tl-btn-secondary are reused
 * verbatim from /css/thinklab.css — this file ONLY adds player-specific
 * layout + state transitions, never re-skins the buttons.
