# Categoria de preço por unidade — espelha o que tava em PricingTables.rb
# como Ruby hash. `key` é canônico ('apartamento', 'standard', etc),
# `aliases` é array de strings que o LLM pode digitar e bate via fuzzy
# match. `extra_person_starts_at` controla a partir de qual hóspede a taxa
# extra começa (default 3 = casal incluso).
