/* The marketing home page (public/welcome*.html, all four locales link this
   one file). 2026-09-26 "stationery" redesign: the page is a desk of study
   stationery, drawn from the app icon (a cream index card with a check).
   - Ink navy text, index-card cream ground, highlighter yellow for the one
     thing to press, a red index-card margin rule, ballpoint blue for links,
     and the icon's teal only for check marks.
   - Every section is a different paper: ruled (hero), dot grid (library),
     plain (how, pricing), and a navy night-desk band (TV, closing CTA).
   - Hard ink edges and small offset "sticker" shadows mark what you can
     press; soft shadows are gone.
   Loaded after /marketing/chrome.css and overrides its tokens for this page
   only (the app and the /sets/ pages keep chrome.css's palette). The dark
   selectors repeat chrome.css's own so they win at equal specificity. */
