/*
  Finite Phone: the sales site's shared stylesheet in the second look (Allen, 2026-11-02, from the
  Round 2 canvas: "it looks great"; docs/website-design.md section 0). A white page, soft rounded
  cards, Inter Tight for headings and Inter for text. Black is the accent (Allen, 2026-11-02: green
  came from one picture's wallpaper, "so i'm not sure if it should be our secondary color"); color
  marks only the app's tools, as the app does: brick for a block, navy for a lock, amber for Second
  Thought, green for a daily limit, grey for In gray.

  Pages move onto it one at a time. A page on it loads this file (the homepage adds home.css);
  a page not yet moved keeps styles.css, the One screen on white look. The shared header, closing
  section and footer are the same markup on both (server/tools/sync-site-partials.py); only their
  look differs.

  Fonts: Inter and Inter Tight, SIL OFL (fonts/OFL-Inter.txt, fonts/OFL-InterTight.txt), variable
  weight, latin and latin-ext, self-hosted under names of our own. Their zero has no slash.
