/**

|
* park-meta.json — persisted alongside the SQLite DB in data/
|
|
*
|
|
* This file stores per-park metadata that doesn't belong in the schedule DB:
|
|
* - rcdb_id: user-supplied RCDB park ID (fills into https://rcdb.com/{id}.htm)
|
|
* - coasters: list of operating roller coaster names scraped from RCDB
|
|
* - coasters_scraped_at: ISO timestamp of last RCDB scrape
|
|
*
|
|
* discover.ts: ensures every park has a skeleton entry (rcdb_id null by default)
|
|
* scrape.ts: populates coasters[] for parks with a known rcdb_id (30-day staleness)
