Step 1: the settings page, read-only, live on NA Ingest at port 8020

Overview (problems in the room with the hold action, the live deck, one line per computer),
Keys (both pages, what each key will say and what holding does), Computers (map with the keys
that turn red, cards with a light per thing that runs there from the watchdog's snapshot and a
read-only probe, Gear, Setup), Logs, History (the installer's copies for now), Help (four cards,
the generated key guide, cheat sheet and Where things are, glossary, Companion facts), Site setup
and Fixes read-only. The editing code is checked (with a lockout) but nothing can change yet.

Also: faults are attributed to the computers their check is about; the installer refuses while a
HyperDeck is recording (--now overrides); the Lighting PC's MIDI session is listed; the probes read
sudo's answer correctly and expand $HOME outside the quotes.

+`http://na-ingest.local:8020/` (the Ingest Mac, LaunchAgent `org.waterschurch.status-settings`, log `~/Library/Logs/status-settings.log`). Anyone on the church network can look: the live deck, every key and what holding it does, every computer and what runs on it (with a light each after "Check computers now"), the gear, the logs, the history, the help pages (What each key does, the cheat sheet, Where things are). Nothing changes without the editing code, which is `site.editing_code` in `config.json`. Step 1 is read-only; editing and Apply arrive with step 2 (see `docs/settings-plan.md`).
+
+The page reads what the watchdog writes next to its config (`snapshot.json` every 5 s, `started.json`, `live-now.json`, `fixes-running.json`) instead of asking the gear again. Its own look at the computers (`settings/probes.py`) runs fixed read-only commands over the same login key, fetches whole lists and matches them here, never while a fix runs.
