+-- 0007_recipe_grounding: a grounded recipe keeps what recipes.Ground
+-- returns, so a stored source_url is reused without fetching or normalizing
+-- it again: its cached photo, and normalize_recipe's method, difficulty and
+-- minutes_total (prep to table; total_minutes stays the page's own JSON-LD
+-- total). Nothing wrote recipes before Ground did, so the columns are added
+-- nullable rather than with a default no recipe has; Ground always sets
+-- photo_id, method and difficulty and refuses to reuse a row without them.
+--
+-- recipe_search_settings gains api_key_last4, the last four characters of
+-- the Brave API key, so the settings can show which key is stored without
+-- ever returning it.
