 ## Construction contract
 
 The host injects everything; the lib never imports `config`:
 
 - `colors` (dict, optional) — per-level colors, merged over defaults
-- `pings` (list of user ids) — mentioned on `critical()`
+- `pings` (list of user ids) — mentioned on `critical()`; the ping content is capped at
-- `timezone`, `footer`, `avatar` — embed identity
+  Discord's 2000-char message limit so a long list still sends
+- `timezone` (`tzinfo`, optional) — must be a real `tzinfo` instance (e.g. `datetime.timezone.utc`);
+  validated at `initialize()`, not a string
+- `footer`, `avatar` — embed identity
 - `alert_here` (bool) — if no `pings` are set, `critical()` falls back to
   `@here` only when this is `True`; otherwise it sends no mention
 - `embed_builder` (callable, optional) — restyle embeds without subclassing
