One HTTP GET per season, no browser: the page is server-rendered, so every row
arrives in one response and the extraction becomes a pure function of the HTML.
- layouts[] declares one profile per version of the site's table (modern and
legacy), each identified by its header row, so a new version of the page is a
new profile plus a fixture instead of a guess.
- The table is located by header signature, not by a CSS path.
- Every cell is shape-checked, and facts the site renders twice (desktop and
mobile date, time in the tooltip) must agree.
- Cross-field invariants: periods sum to the score, ids are unique, played games
always have an event link and unplayed ones never do.
- Output is sorted by date, time and id, so it does not inherit the site's row
order, and it carries no fetch timestamp: same HTML, same bytes.
- Drift is a typed error and exit code 3, with the header it actually found.
- Tests run on committed HTML fixtures and golden JSON; TestLive is opt-in.
