Handler map
===========

The handler files are the implementation reference:

* ``User.go``: identity, sessions, profiles, email, and password flows.
* ``Servers.go``: server CRUD, membership, roles, and standing checks.
* ``Channels.go``: channels, messages, replies, edits, deletion, and invites.
* ``Conversations.go``: DMs, groups, and conversation messages.
* ``Friends.go``: requests and accepted friendships.
* ``Attachments.go``: multipart storage, previews, and access checks.
* ``Reactions.go``: add/remove reaction behavior.
* ``Websocket.go``: connection registries and broadcasts.
* ``Admin.go`` and ``Reports.go``: moderation workflows.
* ``Email.go``: token hashing, SMTP, verification, and reset flows.
* ``HomePage.go``: HTML template handlers.

Handlers should validate input, report database failures explicitly, and
preserve the established status and redirect behavior.
