/* ════════════════════════════════════════════════════════════════════════════
   ZERO · landing/landing.css · THE LIVING SURFACE · the WHOLE CHROME is the instrument
   ────────────────────────────────────────────────────────────────────────────
   No cards. No stream pane. One full-bleed operating surface built in the Söhne
   specimen idiom — a running header line, metadata rows, hairline rules, the
   Narrow live marquee, tabular slashed-zero numerals, acid as the one signal,
   amber the operator accent, and oceans of black. The composer emits intent; the
   reducer (engage.js) recomposes the ENTIRE page per state. The surface IS the
   theater; the surface IS the stream. Loads after colors_and_type.css.

   TYPE wired to the ZERO superfamily (Söhne · Klim):
     · ZERO Wide  (display) — the claim, the instrument's hero figure
     · ZERO Mono  (data)    — every label, value, proof, the composer
     · ZERO Narrow(condensed) — the live marquee, dense tickers
