/* /css/mobile.css — phone fit + touch tap targets.
 *
 * HEROEZ is POINTER-NATIVE: you tap cards, heroes and buttons. There is no
 * virtual stick and no control overlay — the whole job here is (a) making the
 * board fit a phone screen and (b) making every hotspot big enough for a thumb.
 *
 * ORIENTATION NOTE (2026-07-26). This game is NOT gated to landscape, and that
 * is deliberate. Its playfield is a vertical stack — opponent hand, opponent
 * board, message bar, player board, player hand — that needs about 640 CSS px
 * of HEIGHT and only ~360 px of width (the boards and hands scroll sideways).
 * Measured at 844x390 landscape, 0 of 5 hand cards were on screen at all; at
 * 390x844 portrait everything fits with room to spare. The playfield's natural
 * aspect is roughly 0.55:1 — portrait-shaped. So the gate points the other way:
 * see the "turn your phone upright" gate in js/touchFit.js.
 *
 * Loaded LAST so it can override the desktop sheets. Nothing here applies above
 * 900px, so the desktop layout is untouched.
 */

/* ------------------------------------------------------------- tap targets */
/* 44 CSS px minimum on the shortest side, measured at a 390x844 viewport.
 * These apply at every width: a bigger button hurts nobody on desktop. */
