/*
 * EXPERIENCE — phone layout (mobile launch rescue, 2026-10-22).
 *
 * Every rule here is scoped to html[data-xp-layout="mobile"], which
 * src/windows/mobileLayout.ts sets from MOBILE_LAYOUT_QUERY (narrow screens,
 * and touch screens on their side). The desktop layout never matches a rule
 * in this file.
 *
 * The phone layout is an OVERRIDE of the desktop one, not a second system:
 * windows and icons keep the inline geometry the window manager and the icon
 * grid wrote, and the rules below win over it with !important. Nothing is
 * rewritten, so leaving the phone layout puts every window and icon back
 * exactly where it was.
 *
 * Loaded last (after xp.css), so equal-specificity XP rules lose to it.
