 *   brand-red    #D95A2B   warm burnt-orange / vermillion
 *   brand-dark   #0A0A0A   near-black
 *   brand-footer #1A1A1A   very dark grey
 *
 * The brand panel (desktop) is a near-black canvas with a subtle
 * orange glow — visually continuous with the post-login splash so
 * the sign-in → splash → app flow reads as one piece. The form
 * panel stays clean-white in light mode, near-black in dark mode.
 *
 * PWA standalone is the primary target: safe-area-inset padding,
 * touch-friendly hit areas, no browser chrome to lean on.
