/* ==========================================================================
   CostToRunIt design system.

   Concept: the appliance RATING PLATE - the stamped metal label on the back of
   every appliance giving volts, watts and amps. Data is set in monospace like
   a stamped plate; prose is set in IBM Plex Sans. Palette comes from an
   electrical panel: slate ink, cool statement white, filament amber, live teal.

   Rules this file must keep:
   - Pure ASCII. No raw multibyte glyphs (an editor with the wrong encoding
     corrupts them and every page breaks).
   - No @font-face, no CDN, no imports. One request, system-font fallbacks.
   - Mobile first. Every layout rule scales UP from a 320px viewport; the
     desktop rules live in min-width queries, so a phone downloads no
     desktop-only layout work it has to override.
