/*
 * TV / SmartInfo stylesheet (PIN + slider shell).
 *
 * Target: Philips Professional (e.g. 65BFL2214, TPM181HE) — Chrome/49-class
 * OMI engine. Feature tests on device report:
 *   - CSS Custom Properties: NO  → no var(--*), no :root tokens
 *   - CSS Grid: NO               → flex / block only
 *   - Flexbox: YES
 *   - gap: unreliable            → margins instead
 *
 * Keep this file free of Grid, custom properties, :has(), clamp(), oklch(),
 * and env(safe-area-*). Management CSS stays in the split files.
