/* The Pulse Live — full-screen rotating headline board.
   Sibling of css/pulse.css but deliberately separate: the board commits to
   one dark look in both themes and never scrolls. Typography and rhythm
   studied from brutalist.mov (Inter 900 display, wide-tracked mono labels,
   tab-bar chips); the palette is Btown Brief's own — orange / cream /
   brown / teal, with teal reserved for LOCAL. */
