/**
 * One conditional perk pre-loaded into the summary's `perk_cond[8]` table; a consumer
 * evaluates its `trigger` in a ≤8-iteration loop (master §3.4; reference-impl
 * `CondPerkEntry`, record_rs:320-327).
 *
 * Byte-exact to `layout.CondPerkEntryPod` (record_rs:566-577):
 * `perk_id(2) + slot_family(1) + trigger(1) + mag(2) + tier(1) + _pad(1) = 8 B`.
 *
 * `mag` is stored as an **`i16` q-format fixed-point delta** (NOT `f64` — the
 * reference-impl models it as `f64` only in its behavioral mirror; the byte-exact
 * proof and the real program store the raw `i16`, record_rs:319,573). The fold site
 * reconstitutes it into the engine's fixed-point (`PreciseStatVal`) when it sums —
 * the q-format scale + the fold are owned by `folds/`, not by this value object.
 * `slot_family` / `trigger` are raw discriminant bytes (decode via
 * `SlotFamily::from_u8` / `Trigger::from_u8`), kept as `u8` to preserve Pod-ness.
