Following diagnosis in /docs/architecture/indieauth-client-diagnosis.md
and decision in /docs/decisions/ADR-006-indieauth-client-identification.md
Problem: The h-app microformat had hidden aria-hidden="true" attributes
that made it invisible to IndieAuth parsers, causing "client_id is not
registered" errors when authenticating with external providers.
Solution: Remove hidden attributes from h-app div in templates/base.html
to allow IndieAuth parsers to discover client metadata.
This ensures IndieAuth providers can validate our application during
the authorization flow.
