-- Celadon Mansion 3F Game Designer (pokered/scripts/CeladonMansion3F.asm
-- CeladonMansion3FGameDesignerText): text_asm counts set bits in
-- wPokedexOwned and compares against NUM_POKEMON - 1 (discounts Mew).
-- If the player owns >= 150 species, shows the "completed" text
-- (originally followed by DisplayDiploma, which has no equivalent UI
-- in this port, so we just show the congratulatory text); otherwise
-- shows the normal encouragement text.
