/* ============================================================================
   Resources — page components (res-)

   Page-specific layout for the Resources hub and its sub-pages (tutorials,
   FAQ, PDK). Builds on css/wm-dark.css (tokens, bands, wm- primitives), loaded
   first by wm_header() via wm_theme('dark'). A res- component that turns out
   useful elsewhere should be promoted to css/wm-dark.css and renamed wm-.

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