-- Prof. Oak's PC session (#576): engine/menus/oaks_pc.asm OpenOaksPC --
-- the access text, "Want to get your #DEX rated?" with a YES/NO, the dex
-- rating (completion line + tier text), the rating jingle only once the
-- rating text has printed (DisplayDexRating -> PlayPokedexRatingSfx), and
-- the "Closed link to PROF.OAK's PC." tail before control returns.  The
-- old flow played the jingle the moment the entry was picked and skipped
-- both the intro and the closing link.
-- ROM-free: uses the fixture dataset so CI (no data/generated/) stays green.
