/**
 * LOSPOR landing.
 *
 * Deliberately restrained: no photography, no gradients, no drop shadows, no
 * filled cards. Structure comes from whitespace and hairlines, emphasis from
 * type size, and colour appears exactly once — the amber in the brand mark and
 * on the single primary action.
 *
 * The palette is the clinical app's, so the landing and the product it
 * describes look like the same thing: cool near-black surfaces, a soft
 * off-white, and the brand amber from lospor-app/public/brand.
 *
 * Dark follows the operating system. There is no toggle because `_headers`
 * sets `script-src 'none'` — no JavaScript, nowhere to persist a choice.
