## What it does
- POST https://pool-log.rowb.app/api/check  {readings:[...]} — checks readings for impossible values and compares pH,
  free chlorine and bromine with the ranges published on the US CDC pages. No key needed for a few
  checks a day.
- POST https://pool-log.rowb.app/api/sites  — open a log (needs a key). Read it as HTML at https://pool-log.rowb.app/v/<site_id>, or as a
  printable A4 sheet at https://pool-log.rowb.app/v/<site_id>/log.svg.
- GET  https://pool-log.rowb.app/api/rules — the exact rule table and the quoted CDC source of every range.
- It does not decide whether a pool is legally compliant, and it does not use an LLM for anything.
