/* Timber & Brass - the UI look from the menu mockup: dark wood/leather
   panels, thin brass borders with corner brackets, cream text, condensed
   uppercase headings. Type is the two page-wide faces, --font-display and
   --font-body; this file defines no family of its own. Shared primitives
   for the main menu, HUD, shop and build panel; each screen's own layout
   lives next to its markup. */
