/* ============================================================================
   theme.css — Design system for the CEPS09 C208 briefing suite
   "EFB Day-Mode" — an electronic-flight-bag / approach-chart aesthetic.
   Shared by index, perf-decollage, briefing-demi-journee and centrage
   (the last via ../centrage_c208/_write_html.py). Single source of truth:
   tokens + base + reusable components. Page-specific layout stays inline
   in each page but consumes these tokens, so the suite reads as one tool.

   Type   : IBM Plex superfamily — Sans (body), Sans Condensed (instrument
            labels / headings, tracked uppercase), Mono (every readout /
            number, tabular figures — numbers read like cockpit gauges).
   Light by default (sunlight-readable at the airfield). A dark scope
   (:root[data-theme="dark"]) reskins the same components for the landing
   hero / night use.
   ============================================================================ */
