 ## Errors
 
-Resolution failures (unresolvable guild/channel, bad config) raise from `initialize()`
-— a misconfigured logger should fail loudly at setup. The raised type is usually
-`ValueError`, but an underlying `discord` exception (`NotFound` / `Forbidden` /
-`HTTPException`) from `fetch_guild`/`fetch_channel` can also propagate. On a **per-call**
-send, neither resolution nor send failures propagate: they fall back to the stdlib
-logger so a transient Discord failure (or a per-call `guild=` that doesn't resolve)
-never breaks the caller's command.
+Resolution failures (unresolvable guild/channel, bad config, a non-text channel — whether
+passed as an id or as an already-resolved object — or a `timezone` that isn't a `tzinfo`
+instance) raise `ValueError` from `initialize()` — a misconfigured logger should fail
+loudly at setup. Underlying `discord` exceptions
+(`NotFound` / `Forbidden` / `HTTPException` / `InvalidData` and other `ClientException`
+subclasses) from `fetch_guild`/`fetch_channel` are normalized to that `ValueError` on every
+resolution path (construction channel, per-guild settings lookup) so callers see one error
+type. On a **per-call** send, neither resolution nor send failures propagate: they fall
+back to the stdlib logger so a transient Discord failure (or a per-call `guild=` that
+doesn't resolve) never breaks the caller's command.
 
 ## 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()`
-- `timezone`, `footer`, `avatar` — embed identity
+- `pings` (list of user ids) — mentioned on `critical()`; the ping content is capped at
+  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
