/* SpaceSick — The Ones We Barely Know.
   A separate full-screen field of every world we've found: thousands of dim
   placeholder points + the authored worlds as warm lights. Reuses the app's
   tokens. Loaded after css/search.css; adds only new selectors.

   GUARDRAIL: when closed the overlay is opacity:0 + visibility:hidden +
   pointer-events:none (and carries `inert` in markup) — it can never block
   clicks anywhere else in the app. */
