Tactile treats the player as a desk object, not a screen overlay. Before drawing any UI, we modelled a small keypad in Blender: paper-white keys with an ink rim, a ribbed fader cap and a black status display. We pressed it, lit it, and flattened it piece by piece into CSS. Keys latch (1 px down, with a 2 px accent rim), faders scrub, and one display pill always says what the player is doing: PLAY 1.0×, PAUSED, LOADING or END. Play is the only orange key and everything else stays matte, so the dock reads the same over bright snow and a night street. Three glazes and one accent token let it fit someone else's site.
