-- Parity test: the Celadon Mansion roof house blackboard and pamphlet (#391).
--
-- pokered data/events/hidden_events.asm, hidden_events_for
-- CELADON_MANSION_ROOF_HOUSE:
--   hidden_text_predef 3, 0 / 4, 0  PrintBlackboardLinkCableText, LinkCableHelp
--   hidden_text_predef 3, 4         PrintNotebookText, TMNotebook
-- tools/extract/field.py only parses `hidden_event` rows, so neither tile
-- reaches data/generated/field.lua and data/scripts/celadon_eevee.lua carries
-- them as an onInteract hook instead.  LinkCableHelp
-- (engine/events/hidden_events/school_blackboard.asm) prints
-- _LinkCableHelpText1, then loops prompt + 15x10 heading box until B or the
-- fourth row; TMNotebook (school_notebooks.asm) is one plain text.
--
-- Self-contained; run via `luajit tests/parity_celadon_roof_readables.lua`.
