 * it is wired to real data: the palette can only find /pricing because
 * `components/home/shell.tsx` hands it `lib/data/pages.json`, and that file is
 * written at prebuild by walking `app/`. A test in the package would prove the
 * matcher works on a fixture; this proves the site is searchable.
 *
 * The palette's own doors group is one of the three lists it ranks and is
 * asserted below. The header pill is NOT an entry point onto that group — it is a
 * direct link to the Hanzo App, asserted at the end of this file.
 *
 * Against `out/` — the bytes that ship — because the whole chain has to hold:
 * the walk found the routes, the snapshot got bundled, and the palette hydrated.

 * races hydration and the whole suite goes red for a reason that is not the
 * palette. Pressing only while the field is absent means a retry can never
 * toggle a palette that just opened back shut.
