+/**
+ * NewsletterModal — site-wide popup, shown on first visit per 7-day window.
+ *
+ * Behavior:
+ * - Renders nothing during SSR.
+ * - On mount: checks localStorage["bb_newsletter_dismissed"]; if the stored
+ *   timestamp is < 7 days old, stays hidden. Same for
+ *   ["bb_newsletter_subscribed"] (no expiry — never re-prompt subscribers).
+ * - First show is delayed ~5s so it doesn't slam the user the instant the
+ *   page paints; the modal animates from a small pill into the full card
+ *   via the .bb-modal-enter keyframe (defined in tailwind.css).
+ * - Submit POSTs to /api/newsletter/subscribe (existing native endpoint —
+ *   we already have newsletter_subscribers + an SMTP welcome flow there;
+ *   if you decide to swap to Listmonk later, only this fetch URL changes).
