// Anonymous-trial allowance per first-time visitor. Multi-tenant mode
// only. When a visitor lands on the public Recaps URL without a session
// cookie and submits a YouTube URL, the server issues them a
// recap_anon_trial cookie with this many free summaries — no email,
// no signup, no friction. After they're spent, the UI nudges them to
// create an account for more credits.
//
// Trial summaries draw from the OPERATOR's relay credit pool, so this
// number times the visitor volume sets the floor on your sample-cost
// exposure. Tune downward if you see abuse, upward if you want a more
// generous activation funnel. Set to 0 to disable trials entirely
// (visitors immediately hit the sign-up gate).
//
// Defaults to 1 — enough to demo the value prop, tight enough that
// scripted-signup abuse doesn't drain the pool fast.
