Agent rule
Apex and www each show exactly one School CTA — www gets DNS/subdomain note; apex gets meta-footer School line; never both lines on the same hostname.
Status: Accepted
Context: ADR-017 removed personality users liked. Need a hostname-aware rule agents can follow.
Decision: Restore www-only footer note (subdomain + redirect + School as "the why"). Hide general meta-footer School on www via html.is-www.
Consequences: Hostname JS on landing. One CTA per context. Agent checks hostname rules before editing footer.
