/* ============================================================
   Ohmly shared stylesheet, all pages.
   Brand: Ohmly Orange #E55A28 on Charcoal #0B0D10.
   Dark sections carry the argument, Warm White sections carry
   the artefacts (drawings, documents), because the app's own
   canvas is a warm off-white and the paperwork is on paper.

   Contrast rule from Brand Guidelines 5.9: Ohmly Orange holds
   WCAG AA as TEXT only on --bg, --panel and --panel-2. On any
   lighter surface it is a fill with #111111 on top, or large
   text only. Never orange body text on Warm White.
   ============================================================ */
