Review Comment:
Good catch — fixed. Pulled the timestamp math into a shared guarded
`_age_seconds()` so `is_error_cache_ttl_expired`/`is_computing_stale` (and
`is_updated_stale`) all treat an unusable/tz-aware timestamp as expired →
recompute instead of raising. Added tz-aware + unparseable tests for both.
