## This service
- GET https://comptoir.intrane.fr/guide     — the manual, JSON (same bytes as `comptoir guide`)
- GET https://comptoir.intrane.fr/help-json — the command catalog
- POST https://comptoir.intrane.fr/feedback — something wrong? say so. Open, deduped by content.

## Errors
Failures return HTTP 4xx/5xx with a TYPED object, the same shape the CLI uses:
  {"ok":false,"error":{"code":90,"type":"resource","message":"...","recoverable":true,"suggestions":["..."]}}
code/type: 80 input, 90 resource, 100 integration, 110 internal.
`recoverable` is false only for 110 — retrying the same call cannot help.
