/* ==========================================================================
   WILDCARDLABS — RESEARCH LIBRARY (LIGHT, v3)
   Path: public/wildcardlabs.app/frontend/home/subpages/research/research.css

   Same vocabulary as the public entry page, so the two read as one flow:
   - Slim Sora display type over quiet system UI text.
   - Glass plates with a coloured halo for covers and avatars.
   - Hairline section heads with a lit sky tick, ruled rows on a spine.
   - Ambient light, engineering grid and one soft light that follows the pointer.

   Everything is scoped under .wlr / .wlr-* so it can sit next to public.css
   inside the SPA without either sheet touching the other.
