`armada/ui/README.md` was still the stock `npm create vite` text after four pages had
been built in it, so the one file a cold reader opens first said nothing true. It now
lists the five pages and what question each answers, the commands, and the two things
that are easy to get wrong: audio is *mounted* through `audio-mounts.json` (read by
both vite dev and serve.py, so a URL works in both — a UI that only works under `npm
run dev` is a demo), and `kits.json` is generated, uncommitted, and written to `dist/`
as well as `public/`.

The `packs/` README now says where a pack's audio is staged, since it is no longer one
place: kits cut from someone else's stems live beside their source
(`Samples/Fred/output/<kit>/`, `--samples-root`) so the pack stays one movable,
deletable thing, while ParVagues' own kits sit directly under `Samples/`. The bank name
is the directory name either way, so `s "<kit>"` cannot tell the difference.

Then I took a headless screenshot of the page instead of assuming it rendered, which
found three things a typecheck cannot: a legacy kit's filenames are long enough to
truncate with nothing to recover them from (now `title`), the flag filter rendered as a
dead `! 0` on every kit with no flags (now hidden), and the empty-rack text ran the
full width of the screen.
