/* ============================================================================
   Download — page components (dl-)

   Page-specific layout for the download hub and the install/run guide. Builds
   on css/wm-dark.css (tokens, bands, wm- primitives), loaded first by
   wm_header() via wm_theme('dark'). A dl- component that turns out useful
   elsewhere should be promoted to css/wm-dark.css and renamed wm-.

   Loaded with a cache-busting query (controllers/download.php passes
   css/download-dark.css?v=N) — bump N when editing this file.
