/* ==========================================================================
   Karti Kidambi — Portfolio v2
   Design system: dark-first, with a persisted light theme.

   Theme model
   -----------
   :root carries the DARK palette (the brand default). The light palette is
   defined once, in a custom-property block reused by two selectors:
     - [data-theme="light"]                     -> explicit user choice
     - prefers-color-scheme: light, un-overridden -> system default
   Every colour is a token. No component below hardcodes a hex value, so a
   third theme would only need one more block.
   ========================================================================== */

/* --------------------------------------------------------------------------
   1. Tokens

   Palette: three colours, used for what each is physically capable of.
     #092328  petrol black  — deepest. Body text on light; the canvas on dark.
     #0F3040  petrol navy   — mid. The brand accent on light; raised surfaces
                              on dark.
     #F9E8A2  champagne     — near-white at 0.80 luminance, so it can never be
                              text on a light ground (1.2:1 against white).
                              It earns its keep as a FILL with petrol text on
                              top, and as the accent on dark where it reaches
                              13:1. Every use below respects that.

   Light stays the default, as agreed. Dark is opt-in and is where the palette
   is most itself: petrol black canvas, navy cards, champagne accent.
