/* Hey Reachy — marketing site.
 *
 * The palette is the app's own `graphite` theme, which is `ReachyTheme.fallback` and the
 * icon the README shows: accent #3E4757 light / #A9B6CC dark, with the icon's own gradient
 * stops #9AA6B8 → #3E4757 carrying the hero. Keep these in step with
 * Sources/ReachyDesign/ReachyTheme.swift if that palette ever moves.
 *
 * System fonts only, and nothing loaded from another host — a page claiming the app collects
 * nothing should not itself phone home for a typeface.
