-- Per-city planner defaults for the financial calculator.
-- When a user selects a city in the planner, these values pre-fill the inputs.
-- Consumed by: padelnomics.planner.routes — /api/market-data endpoint.
--
-- 3-tier data cascade:
--   1. City-level: real pricing/occupancy from Playtomic availability snapshots
--   2. Country-level: median across cities in same country
--   3. Hardcoded fallback: market research estimates (only when no Playtomic data)
--
-- Units are explicit in column names. Monetary values in local currency.
