/* Krillion+ — one layout, three visual worlds. Mobile first; two columns on desktop.
 *   flat  (default)  "dive computer": cool paper, ink-dark instrument hero, monospace readouts; follows OS dark mode
 *   pop              "dopamine 3D": candy colour blocks, rounded Fredoka, extruded toy buttons, glossy icons
 *   pixel            "16-bit RPG": Sweetie 16 palette, Fusion Pixel font for every script, menu windows,
 *                    bevelled A-buttons, a night sea of our own sprites
 * Components read tokens only; each theme is a token block + a short signature block at the end.
