/*
 * Public landing page styles (Landing Phase) — entirely namespaced under
 * `.landing-*` classes so nothing here can leak into or collide with the
 * authenticated dashboard's own CSS (`shell.css`/`dashboard.css`, neither
 * of which this page loads at all). Reuses `tokens.css` custom properties
 * exclusively for color/type/space/radius/shadow — no new hardcoded
 * values, no new color system, so the page stays visually part of Monitor
 * (including automatic dark-mode support via the same `[data-bs-theme]`
 * tokens every other page already uses) while still being free to be
 * more spacious/marketing-oriented in layout than the dashboard shell.
