/* ============================================================
   EventFlow Pro · "Signal" theme (global overlay)
   Works on top of the Tailwind CDN runtime build.

   Design language: architectural precision over generic glass.
   - Solid, crisp surfaces with 1px hairlines (no translucent blur)
   - Deep-ink side rail with a brand "signal bar" on the active item
   - Fine blueprint grid background, one restrained brand glow
   - 2px brand "signal line" on the top edge of headers
   - Editorial micro-labels + tabular numerals
   Selectors deliberately mirror common view class combos so the
   whole app upgrades without touching every template.
   ============================================================ */
