/* EVeryWatt design system - "instrument" direction B (petrol ink + filament amber).
   Order: tokens, base, icons, header, layout, controls, instrument panel, summary/sheet, menu,
   then one section per page. Colours are used by ROLE, never by hue name:
     ink / on-dark   the dark instrument surfaces and their text
     signal          the amber glow: charge level, selected charge, the wordmark's "EV"  (dark surfaces only)
     action          primary buttons (ink) - amber is too pale for text/buttons on the light page
     series          the one chart line colour on light cards (a deeper bronze, validated >= 3:1)
     ok / soon / over  status; always paired with an icon and a word, never colour alone                */
