/* ==========================================================================
   toddreboul.com — encyclopedic design system
   Wikipedia's information architecture, rebuilt as warm editorial neutral.

   Palette intent: paper and ink, not screen and pixels. A warm off-white
   stock, warm charcoal text, deep navy for authority, brass for accent.
   Dark mode is a warm graphite — the same system with the lights off, not a
   cold blue-black. It only appears if the reader's OS asks for it, or if they
   pick it from the toggle.

   No dependencies. No build step. Edit § 1 and the whole site reskins.
