/**
 * PixelSwarm shared UI: chamfered carbon control (landing menu button look).
 *
 * - .ps-carbon-btn — default gray carbon face (use with Bootstrap .btn on index/app).
 * - .ps-carbon-btn--primary — Hive red fill (with .btn.btn-primary).
 * - .ps-carbon-btn--pizza — orange HivePizza CTA (index).
 * - .ps-carbon-btn--vivid — brighter saturated red (use with --primary, e.g. paint submit).
 * - data-ps-press-sfx — click / Enter / Space sound (pixelswarm-ui.js + initPressSfx).
 *   Themed faces use ::before — use <button type="submit">, not <input type="submit"> (no ::before in WebKit).
