/* point.free — newsletter subscribe card.
 *
 * Floating bottom-right card injected by /static/newsletter.js. The card is
 * deliberately quiet: hairline border, subtle blurred background, monospaced
 * label and button — the same vocabulary as .home-byline, .home-section-label,
 * and .home-elsewhere so it reads as part of the site rather than a SaaS
 * widget bolted on.
 *
 * Lifecycle (state is in localStorage, see newsletter.js):
 *   first visit          → shown after dwell + scroll thresholds
 *   user dismisses       → suppressed for ~14 days, then re-shown
 *   user subscribes      → suppressed forever (double opt-in handled by Plunk)
 *
 * Markup contract — newsletter.js builds exactly this:
 *
 *   <aside id="newsletter-card" class="newsletter-card" aria-live="polite">
 *     <button class="newsletter-close" aria-label="Dismiss">×</button>
 *     <p class="newsletter-eyebrow">Newsletter</p>
 *     <h3 class="newsletter-title">Quiet notes, sent rarely.</h3>
 *     <p class="newsletter-desc">…</p>
 *     <form class="newsletter-form" novalidate>
 *       <label class="visually-hidden" for="newsletter-email">Email</label>
 *       <input id="newsletter-email" type="email" required placeholder="your@email.com" />
 *       <input id="newsletter-trap" type="text" tabindex="-1" autocomplete="off" />
 *       <button type="submit" class="newsletter-submit">Subscribe</button>
 *     </form>
 *     <p class="newsletter-status" role="status"></p>
 *   </aside>
 *
 * The honeypot input lives inside the form but is positioned off-screen
 * (not display:none, because some bots skip display:none fields). Real
 * users never see it; bots fill it and we silently swallow the submit.
