pub fn transform_all_racial_spells(dbc: &DbcData) -> Vec<RacialSpellFlat>Expand description
Expand every racial skill-line ability into one RacialSpellFlat per race that learns it.
Mirrors SimC’s RacialSpellSet (dbc_extract3/dbc/filter.py:29) and its generator.
A row with no race mask of its own inherits the skill line’s, which is how Pandaren are keyed.
