# Run the daily-file scrape and then serve the dashboard.
#
# Usage:
#   ./start.sh              # scrape today, then serve on :8000
#   ./start.sh --force      # force re-fetch even if cached
#   DATE=2026-09-01 ./start.sh   # scrape a specific date
#
# Environment overrides:
#   DATE        - YYYY-MM-DD to scrape (default: today)
#   PORT        - dashboard port (default: 8000)
#   HOST        - dashboard bind address (default: 127.0.0.1)
#   FORCE       - set to 1 to pass --force to ingest
#   SKIP_SCRAPE - set to 1 to skip the scrape step entirely
