/**
 * Project feedback channel.
 *
 * There is no server and no tracker (see the About modal — no telemetry of any
 * kind); feedback is a plain email the user composes and sends from their own
 * client. The address is a Cloudflare Email Routing alias that forwards to the
 * author, so it can be retired without exposing or churning a personal inbox.
 *
 * Shared by the Support modal and the About modal — a contact address is worth
 * a single source of truth so the two surfaces can't drift.
