"""
Manager ABCs for streaming providers.

Each manager wraps one capability area with a fixed public interface.
Providers subclass and implement the abstract methods; the concrete
methods (headers, DRM defaults, search no-ops) come for free.

Design rules
------------
* Constructors take four required collaborators -- http_manager, auth,
  country, config -- plus keyword-only extras (caches, collaborators).
* Managers never hold a reference to the provider. Shared state is passed
  in at construction.
* Managers raise from base.errors; nothing catches broadly.
* VOD navigation always returns VodPage (base/vod.py).

On the None-vs-exception rule
-----------------------------
Manager top-level methods signal "this manager doesn't handle that
content_id" by returning None / [] -- NOT by raising NotFoundError.
See providers/_template/README.md for the full rule.

Rigidity note
-------------
The ABCs enforce the *method names and signatures* through the abstract
method mechanism. They do NOT enforce that providers raise the right
error classes, or that they return the right content shapes. Those are
conventions documented in the template.

Manager list
------------
Three required capabilities:
    ChannelManager
    VodManager        (providers without a browseable catalogue return None)
    EpgManager        (providers without EPG return None)

Four optional capabilities -- providers implement the ones they support:
    RecordingsManager  (cloud / network PVR)
    FavoritesManager    (user bookmarks on programs / channels)
    BookmarksManager    (resume position)
    CatchupManager      (timeshift / restart)

Providers signal a capability's presence by whether _build_*() returns
a manager or None. Capability flags (implements_vod, implements_epg,
implements_recordings, ...) are derived from that.
