/* web/schedule-opcenter.css
 *
 * PR-OPC-1 (2026-05-25) — Siemens Opcenter APS aesthetic for the
 * Schedule page rebuild. Scoped entirely to `#pg-schedule-v2 .opc-*`
 * — zero selector collision with the existing `#pg-schedule .schedp-*`
 * stylesheet that lives in web/schedule3.css.
 *
 * Goal: industrial-terminal flat-panel look. Hairline 1px borders,
 * zero rounded corners on functional surfaces, tabular monospace
 * numerics, 28px sticky bottom status bar, dense 4-line cards.
 *
 * Strict color tokens only — every color is `var(--token)` or
 * `color-mix(in srgb, var(--token) X%, var(--bg))`. No hardcoded hex.
 * Tokens defined in index.html lines 368-426 for both Studio Light
 * and Onyx Dark.
 *
 * Sign-off gates (from QA package):
 *   GATE-1: stranger reads 5 items in ≤5s
 *   GATE-2: zero hardcoded hex
 *   GATE-3: drag-drop preserved
 *   GATE-4: footer visible after scroll
 *   GATE-5: theme switch no anomaly
 *   GATE-6: third-party calls "clearly different visual styles"

/* PR-OPC-2-FIX (2026-05-25): only paint the page when go() has added
   .on — earlier OPC-1B shipped this as a bare `#pg-schedule-v2 {…}`
   rule whose id-specificity (1,0,0) clobbered `.pg{display:none}`
   (0,1,0) from index.html line 943, so the schedule grid leaked onto
   Home / Libraries / every other page underneath. Pairing display
   with `.on` restores the standard `.pg` visibility contract. */
