/* ==========================================================================
   Typeme — line-grid editorial page.

   The layout borrows the line system from the english-game landing page:
   every section is a band between two long vertical rails, closed by a
   horizontal rule, with a square "nail" where the rails meet the rule.
   Content sits in shared-border grids instead of floating round cards.
   Dot / hatch / stripe patterns are used only as quiet texture.

   Palette: neutral paper, ink, grey lines, one coral accent. The app icon
   supplies the only saturated colour on the page. A light/dark theme is
   switched with [data-theme="dark"] on <html>.
