/* Elevation. The source file uses NO shadows anywhere — zero effect styles, zero blurs.
   The system is deliberately flat: depth comes from value contrast and hairline borders.
   The two shadows below exist only for genuinely floating UI (dialog, popover, toast) and
   are authored, not sourced. Prefer a border first. */
