/* ---------------------------------------------------------------------------
   Lamplight, on the web.

   The app's surface (Roommates/Shared/Lamplight.swift) in a stylesheet, so the
   privacy policy and terms read as part of the app rather than as a generic
   legal page bolted to the side of it. Three things carry over verbatim:

     • The palette is OKLCH, not hex — same numbers as Lamplight's `Color.mode`
       pairs, so a hue is a hue in both places. Browsers have shipped oklch()
       since 2023; a hex fallback sits above each one for anything older.
     • Schibsted Grotesk for everything readable, Martian Mono for eyebrows —
       the same static per-weight cuts the app bundles, converted to woff2.
     • Light and dark are peers, chosen by the reader's system.
