Sessions last 4 hours, and we say why

Marty's call. Sign-ins expired after 24 hours, which meant a member passed
the login gate roughly once a day — and that gate is the entire inventory
behind the login-ad product. The platform has served 356 login impressions
in its life while members have bought 20,526 credits of them.

Four hours, env-tunable via SESSION_TTL_HOURS.

Said out loud in three places rather than left to feel like a glitch:
the login gate itself now explains it, the chatbot has a canned answer for
"why do I keep getting logged out", and the same fact is in the assistant's
system prompt so the AI never calls it a bug. Wording throughout is
Marty's: to keep resources optimised we do not keep anyone signed in
longer than 4 hours, and nothing about the account, credits or line is
affected.

The canned pattern was checked against the neighbours it sits beside —
seven phrasings reach it, and withdraw / pyramid / earnings / second
account / payout answers are all untouched. CANNED is first-match-wins,
so that check matters.

Member walk clean, chatbot suite 35 green.
