Captures everything since website-1: the ADR-namespace move, all Reference +
Guides + the new SQL queries page, the cast pipeline + 7 casts (incl. the new
projects cast via #24 vi-nav), --demo on all casts (#22), and the main merge
(m:n/ADR-0045, UI sidebar+responsive input/ADR-0046, demo overlays/ADR-0047,
logging, FK fixes).
Flags the next-session work: document the merge's new features (m:n command,
--demo flag, ADR-0046 UI) which are not yet in the docs; the no-advertising
constraint (vi keys / Ctrl+] secret); cast tooling limits (no arrow keys);
the capture-harness recipe; Phase B; and open STYLE decisions.
