/* ============================================================
   Treehouse — bundled UI typeface (fonts.md Phase A)

   Lato, self-hosted. Same face Slack ships, chosen for readability
   across sizes/resolutions and because it is SIL Open Font License
   (OFL) — free to bundle and redistribute (see fonts/lato/OFL.txt).

   Self-hosting (not a CDN, not a system install) means the UI renders
   identically on every operator's machine — macOS, Windows, a
   hardened Linux ops terminal — and works fully air-gapped.

   Two weights carry the whole hierarchy: Regular (400) and Bold (700),
   each with its italic. `font-display: swap` paints immediately in the
   fallback face and reflows to Lato when the woff2 lands.

   Files are split latin / latin-ext subsets so a deployment that only
   needs ASCII pays ~14KB/weight, with accents lazy-loaded on demand
   via the unicode-range hints.
