AUTH_0 signs in in the browser (authorization code + PKCE with the API
audience, code exchanged at the tenant, the token handed to manageSession)
and can end the Auth0 session on sign-out. F1 uses the kernel's help
entries (app, widget, instance, table, process, step) with readable places;
:helpkeys shows every help slot key. The grid footer shows the column's
help. scripts/perf-large-table.sh times a 10,000 x 40 table on the fake
large-instance server: first page ~100 ms, record 10,000 ~40 ms, column 40
~350 ms. Parity: TUI 330 pass, 67 n/a, 3 blocked, 1 todo (SEC-030: needs a
real Auth0 tenant).
