/* ═══════════════════════════════════════════════════════════════════════
   inv.geo.rs — the front door.

   It hands off to the viewer and the deck, so it keeps their ground, their
   ink and their one accent: a visitor who clicks through must not feel the
   page change hands. What it does NOT share is the type. The tool uses the
   operating system's own sans because a tool must render identically with
   the network unplugged; the front door is allowed a voice, and it is set in
   faces served from this box — no CDN anywhere in this project.

   The four band colours are the only other colours on the page, and they
   appear exactly once, in the bar that IS the result: distance from a
   candidate kerb to the nearest surveyed line. They are data. Nothing here
   is tinted with them for decoration.
   ═══════════════════════════════════════════════════════════════════════ */

/* ── the faces ───────────────────────────────────────────────────────── */
/* Big Shoulders is the condensed grotesque the deck already reaches for with
   a system stack; here it is the real thing, and its narrow set lets a true
   sentence run very large without breaking into a slogan. Plex Sans and Plex
   Mono are IBM's engineering faces -- the right voice for a page read by
   surveyors. Both are variable: one file, every weight. */
