/* Feature #5 — Categorized icon-tile launcher.
   All styles scoped under .guide-launcher so this file is safe to load
   alongside app.css / public.css without clobbering anything.

   Brand: green #0b4f55, gold #c5a059 (light) / #d7b56d (night).
   Works on default palettes and on .guide-palette-night (the article
   carries that class, so .guide-palette-night .guide-launcher matches). */
