-- Parity test: the Hall of Fame dex rating runs through the standard
-- PrintText text box (#314).
-- Self-contained: run via `luajit tests/parity_hof_rating.lua`; also
-- dofile'd by tests/run_tests.lua's aggregator.
--
-- pokered's HoFDisplayPlayerStats (engine/movie/hall_of_fame.asm) prints
-- three texts back to back through HoFPrintTextAndDelay -> PrintText, each
-- followed by 120 DelayFrames: _DexSeenOwnedText, _DexRatingText
-- ("POKéDEX Rating:"), then the tier line copied into wDexRatingText by
-- DisplayDexRating (engine/events/pokedex_rating.asm).  PrintText is the
-- standard two-row bottom box, so the tier text's `cont` (\v) rows scroll
-- inside it -- each with the original's ▼ + A/B wait (_ContText ->
-- ManualTextScroll), even mid-ceremony.
--
-- The port instead hand-drew a 6-row box and flattened \v into plain
-- newlines with drawTextBlock, so a 3+ row rating ("You finally got at /
-- least 50 species! / Be sure to get ...") painted its third row on top of
-- the bottom border and dropped the rest (#314).
--
-- The invariant: after the stat boxes, the induction pushes TextBox states
-- for the seen/owned counts, the "POKéDEX Rating:" header, and the tier
-- text, in that order, and each closes itself after the 120-frame hold.
