/* IGNIS: dark scientific theme (theme locked dark, brand colorway kept).
   Structure follows the Linear design system (awesome-design-md/linear.app): surface ladder + hairlines, no gradient fills,
   lifted panels get a 1px top edge highlight, negative tracking on display type, 56px nav.
   Radius: panels 16px, cards 12px, buttons / inputs / images 8px, status pills (chips, badges, tabs) 999px.
   Colors: every value comes from the tokens below; no literals in rules.
   Accent: blue (--accent) for interaction; flame orange (--flame) only for hero / key-number highlights. */
