2//! Tag-resolution helper. Reads `Trace` once into a static
3//! list, then matches against four rules per call:
4//!
5//! 1. Explicit tag match always wins.
6//! 2. `Trace=all` opens every tag.
7//! 3. `Trace=short` opens every tag *except* the firehose-mute list
8//!    (`SHORT_MODE_MUTED_TAGS`).
9//! 4. Otherwise the tag is closed.
