/* ============================================================================
 * MINER BOSS — landing page presentation (v6.6 "Kapı").
 *
 * The tokens are the GAME'S, lifted from css/style.css: sooty coal ground,
 * lantern amber from above, brass edges, paper ink; money is gold, the primary
 * action is ember orange, $MINE is mineral cyan. Jersey 10 is the display face
 * the game uses, loaded from the repo — no CDN.
 *
 * Every sprite is drawn with image-rendering: pixelated at a multiple of its
 * source size (--px: 2 on desktop, 1.5 on phones), so the pixel art stays
 * crisp. The cross-section in the hero copies js/scene.js: miner frames
 * toggle on the game's 0.72 s swing (raise 55 % / strike 45 %), the pickaxe
 * sits at the game's grip points and angles (raise −1.15 rad at (+4,−31),
 * strike 1.4 rad at (+10,−18), shoulder −0.8 rad at (+2,−20), scale .9/.85),
 * debris flies on the strike, the cabin, cable and wheel share one timeline.
 * Dark only, like the game.
