/* town-hud.css (TW7; town DESIGN §2.2, §2.3): the island HUD on the core tokens. Every selector names a tw- class.
   Town buttons are circles: big 104 (6-8 Action), main 92 (9-10 Action), side 84, small 68, card 60; nothing below the core
   60 px target. Tablets (shortest side >= 700 px) scale every Town button by 1.15 with 24 px margins. Every position adds
   env(safe-area-inset-*); the bottom 24 px stay free for the system bar. The press: a scale to .94 in one frame
   (.is-down, set in the pointerdown itself) and back on the token spring over --t-micro. Hidden controls fade out (180 ms).
   Positions (phone, portrait): 6-8 Toy Box 84 at left 16 / bottom 32, Action 104 at right 20 / bottom 40, Wish 68 at
   left 16 / top 96, Sun 64 at top 16 centred; 9-10 Wish at top 96, Toy Box 68 at top 176, Action 92 at right 20 /
   bottom 36, Jump 84 centred 80 px left of and above Action's centre. Landscape: Sky and Wish top left, the Sun top centre,
   the Toy Box and Action at the bottom corners 24 px up; 9-10 puts Toy Box and Wish in the top row (clear of the joystick
   zone, freecam.inJoyZone) and Jump 76 px off Action's centre; the landscape Sun is 60 px (§2.3 says 56, under the core
   60 px target). hud.js logs these deviations from §2.3. */
