/* AI ThinkLab / Runesmith: one stylesheet, no build step, no web fonts, no external requests.
   It follows the Studio's look and the logo kit: slate and deep slate, gold, a faint gold grid, corners cut at 45 degrees
   with a hairline that follows the cut, Bahnschrift (or the system face) for display, restraint everywhere else.
   A clip-path hides anything outside the box, so keyboard focus on a cut box is an inset gold glow, never an outer ring. */
