/* Pricing. Added 2026-08-31, after the owner lifted the brief's ban on naming
 * a price. See web/REDESIGN-BRIEF.md for the grant and the four approved tiers.
 *
 * The paid tiers carry a เร็ว ๆ นี้ pill instead of a checkout button, because
 * there is no payment system behind them: src/ has an optional `plan` string on
 * a quota row and nothing else. A button that goes nowhere is the same defect
 * as a link to a host that does not exist. */
