-- benilla's own: tolerate the server's AIO blocks this client has no feature for.
--
-- AIO dispatches a server block by name through `AIO_BLOCKHANDLES`, and an unregistered name is
-- an `error()` (`AIO.lua:547-549`). That is the right shape — except **pfUI replaces the global
-- `error` with one that prints to chat and returns** (`pfUI.lua:453-460`, which it does to feed
-- `seterrorhandler`). A non-raising `error` turns AIO's clean abort into a fall-through: the
-- next line calls the handler it just failed to find, so the player sees two errors, the real
-- one being `attempt to call local 'handledata' (a nil value)` at `AIO.lua:558`.
--
-- That is pfUI's bug and it would bite the reference client the same way; what changed here is
-- only that benilla now loads AIO at all (for the calendar). So the blocks this client does not
-- implement are registered as no-ops, which is what "no handler" was always supposed to mean.
--
-- `IGNORED` is empty, and the shape around it is what matters. `AIO.RegisterEvent` *asserts* when
-- a name is already taken (`AIO.lua:736`) and AIO has no way to unregister, so a name claimed
-- here is claimed against every later registration — including the realm's own, if a client
-- update implements the block we were standing in for. That is not hypothetical: this file used to
-- claim `OctoRadio` on the evidence that `OctoRadioPlaceholder.lua` carried no AIO call at all,
-- and the 2026-10-23 update built the radio out into a file twice the size whose
-- `RegisterNowPlayingFeed` registers exactly that name at `VARIABLES_LOADED` — ten tests' worth of
-- raise, from a row that had simply gone stale.
--
-- Hence both halves below. The claim waits for `PLAYER_LOGIN`, after the `VARIABLES_LOADED` where
-- FrameXML and addons register and before any block can arrive, and each name goes through
-- `pcall`, so a realm that implements one of these takes the name and this file steps aside
-- instead of raising. `reference_ui`'s tests fail a row the realm has implemented, so the next one
-- is caught in the gate rather than in a session.
