/* The public landing page (templates/landing.html, webapp/views/landing.py).

   Light, centred and plain: white, one soft grey, a hairline border, and the product's own blue
   for anything that can be clicked. The page is read once, on a cold connection, often on a
   phone, so there is one small self-hosted web font (the headings, below), no images beyond the
   logo, and no video.

   **Nothing here animates and nothing here is scripted.** The page has no script tag at all;
   the questions open with `<details>`. Hover and focus change colour and nothing else. If motion
   is ever added back it belongs behind a class a script adds, so that a page without the script
   is still the finished page - but for now there is none to add it.

   Colours come from the tokens in style.css. `templates/landing.html` sets `data-theme="light"`,
   so the `:root` block there - not the dark override - is what these var() calls resolve to.

   Verify with `uv run python scripts/layout_probe.py --render --measure --pages landing`;
   tests/test_landing_page.py pins the promises, the prices and the no-script rule. */

/* The headings' one web font, served from here rather than from Google (2026-10-01). A visitor's
   browser fetching it from fonts.googleapis.com sends their IP address to Google before they have
   agreed to anything - a German court fined exactly that (LG Muenchen I, 3 O 17493/20, 2022) - and
   the Cookie Policy says no third party is contacted while this page loads. Plus Jakarta Sans,
   SIL Open Font License 1.1 (static/fonts/plus-jakarta-sans/OFL.txt); 700 only, Latin and
