"""Tests for sitemap API endpoints — /api/sitemap/sitemap.xml, /api/sitemap/robots.txt, /api/sitemap/regenerate.

Note: The sitemap and robots.txt endpoints now read the site URL from
StationConfig.website in the database (falling back to KMTN_WEBSITE_URL
if the config is missing). These tests assume a seeded database with the
default station config (website = 'kmountainflower.org').
