/* ============================================================
   KONSTELASI.CSS  —  regulasiku.id front page
   The search box (combobox) and the constellation panel (3D graph of
   regulations and their relations), plus the crawlable key-laws list.
   Used by index.html only, together with _js/konstelasi.js.

   Every class is prefixed "ks-" so nothing here can collide with the
   front page's own inline styles (e.g. its .pill) or a shared sheet.

   The site has no dark mode. The page stays light; the panel has its
   own light and dark palette (.ks-sky[data-mode]) which follows
   prefers-color-scheme unless the panel's own ☾/☀ toggle overrides it.
