The options were buried in three prose bullets that mixed mechanism, cost and
coverage, so the one question that matters — which attacker each variant stops
— could not be read off the page. They are now a table: four scenarios by
three variants, with the cost and the caveats underneath and the scenario
prose moved below the table for whoever wants the detail.
No change of substance: same variants, same recommendation (the Origin /
Sec-Fetch-Site check in the phase 14.A middleware), same caveat that a naive
double-submit token leaves the subdomain row open.
