   template7.css — PlanetContent
   A dark "night" canvas: white portal masthead with a centred wordmark and
   search, a deep-green topic bar, a glowing hero, a bento mosaic of featured
   stories and horizontal shelves per topic. Emerald accent from the wordmark.
   The only dark-canvas template; every other new-look template is light.
   Loaded after astro-ui.css; only re-declares tokens plus a few signatures.
