/*
  Glazzy on the web: glazzyapp.uz.

  THESIS      A page you can use: the first thing on it is a check to tap, because one
              tap is the whole of Glazzy. Not a grid of feature cards.
  OWN-WORLD   The App Store screenshots' sticker sheet: lime with a dot grid, ink
              outlines, hard offset shadows, capsules, sparkles and pen strokes. The
              habits' own tints color what's tapped. Cards are 28px, as in the app.
  STORY       Tap, and a day is checked off. Scroll, and it adds up: goals, reminders
              that go quiet, twelve weeks filling. Then: it's private, and it's free.
  FIRST VIEW  The tag, the headline with "stick" on its sticker, one line, the check to
              tap, and three phones fanned on the section's edge.
  FORM        A long sticker sheet: lime, paper, a band, the ink block, lime again.
              The policy and support pages stay one reading column.

  The colors are the app's own, copied by value. Measured (WCAG): ink on paper 15.5:1,
  secondary 8.5:1, links 6.5:1; in dark mode text 15.5:1, secondary 9.1:1, links 12.6:1;
  ink on lime 12.6:1.

  No script, no font and no image from anywhere else. What moves is CSS, and what's
  tapped is a checkbox or a radio button.
