/* ==========================================================================
   Launch Labs — "THE SHIFT": an editorial, typographic moment — not a UI card.
   Still the first beat revealed out of the hub's zoom-to-black hand-off (see
   js/shift.js) — same midnight navy/black atmosphere as the hero. A large,
   generous composition (~70-75% of the viewport): the headline is the visual
   anchor, sitting directly on the atmosphere with no glass around it; only the
   equation sits inside a quiet smoked-glass pane that reads as emerging from
   the background rather than a bordered container. Plus Jakarta Sans for the
   headline + statements, Hanken Grotesk for the eyebrow; Launch red (#D92632)
   on the eyebrow and the +/= markers only. Namespaced .shift.
