Ashen Vow ships no Progressive Stages rules.

Progressive Stages generates ~50 example stages here on first run, all with
"showcase:" rule ids. They are the mod's own demo content, not pack content,
and Ashen Vow grants none of them - so everything they lock stays locked
forever. Among other things they lock the Nether portal and lava, which makes
the quest book's own Act V ("Through the Black Door") impossible to finish.

They also caused a hard client hang: the JEI plugin registers an ingredient
listener, hiding locked fluids fires it, the listener schedules a refresh, the
refresh re-adds the ingredients, and the listener fires again. The render thread
logged "Ingredients are being added at runtime: 32 FluidStack" every ~4ms
forever, so the terrain screen never finished even though the world had loaded.

This directory is intentionally empty apart from this file. If you want stage
gating, author real stages here and grant them from the quest book - do not
keep the generated showcase set.
