/* ==========================================================================
   avaknightly.com — Design System
   "Cozy workshop + LitRPG" identity for a cozy-crafting LitRPG author site.

   Palette (binding): parchment #f6efe3 · ink #2a2118 · brass #8a6d3b ·
   amber #c9974b · ember (CTA) #c2431f · dark-mode bg (umber) #221a12.
   Type: serif display = Georgia / Iowan Old Style stack (also used for
   reading body copy, for a warm literary feel); monospace = Consolas,
   Menlo, monospace (LitRPG "system box" identity: .statbox / .bluebox);
   a small system-sans stack is used only for compact UI chrome (nav,
   badges, buttons) to keep interactive elements crisp at small sizes.
   System font stacks only — no @font-face, no webfont downloads.

   Mobile-first. 375px is the primary target; layouts widen at 701px+.
