/* Ollanders Sci-Fi — "Bold Poster" design system.
   Memphis/poster aesthetic: warm ivory paper, ink black, a tight saturated trio
   (yellow / sky-blue / coral). Two shadow languages — hard offset "sticker"
   shadows (border + pill) for interactive things, and a soft floating shadow used
   ONLY on the semantic profile cards. Bootstrap is loaded for reset/grid only;
   everything visual here is hand-written. Tokens first, then components.
   Sizes are set ~15% below the source spec (the spec read too large on screen);
   the 3px ink borders are kept full-weight so the sticker look survives. */
