/* Vula Systems - "Paper Intelligence" design system.
 *
 * Palette, component classes and print rules, shared by every page. Extracted
 * from the <style> block that used to sit inline in index.html so the legal
 * pages can use the same system instead of duplicating it.
 *
 * Every colour is an RGB triplet in a --c-* variable, which is what lets .dark
 * swap the whole palette without a second set of classes, and what lets
 * Tailwind's opacity modifiers (bg-paper/90) keep working. Retuning a colour
 * here needs no stylesheet rebuild.
 *
 * Loaded BEFORE assets/tailwind.css on every page - utilities must win ties.

   PALETTE
   --------------------------------------------------------------------------
   Values are space-separated RGB triplets, not hex, because Tailwind composes
   them as rgb(var(--x) / <alpha-value>) to support bg-paper/90 and friends.
   Dark mode redefines the same names — no component below needs to know which
   theme is active.
