/* ----------------------------------------------------------------------------
 * The landing page.
 *
 * Shares the app's colour tokens so the two feel like one product, then sets
 * its own rhythm: bigger type, more air, made to be read on a phone in a school
 * corridor.
 *
 * ⚠ EVERY SIZE, SPACE AND RADIUS IS A TOKEN from system.css, which must load
 * first. This file had fifteen ad-hoc font sizes, three radii and thirty-five
 * spacing values of its own on 8 Oct 2026 — and it is the FIRST page anybody
 * sees, so it was the worst place in the product to be improvising. A new raw
 * value here is a bug, not a style choice.
 *
 * ⚠ EVERYTHING IS SCOPED UNDER .landing. `.band` means something else in the
 * app — the four sections of the home screen — and these rules load after
 * system.css, so an unscoped `.band` here would quietly reach into the app if
 * the two stylesheets were ever loaded together.
