Mobile fixes (article, guide, get-to-know, projects pages):
- Remove duplicate main.js include site-wide. footer.js emitted a
<script src=main.js> inside the footer block while pages also load one
before </body>, so DOMContentLoaded ran twice and every tap toggled the
mobile menu / article TOC twice (net no-op). Menu and TOC only worked on
the homepage. Now exactly one main.js per page, before </body>.
- Kill horizontal overflow: add overflow-x: clip to html/body (clips the
off-canvas mobile nav panel without breaking position: sticky, unlike
overflow-x: hidden).
- Reset align-items to stretch in the mobile .article-layout-container
rule; the desktop flex-start made .article-container size to max-content
width in a column flexbox and overflow the viewport.
Membership form hardening (Become a Member):
- Honeypot field + localStorage cooldown (30s gap, max 3/24h) + stronger
email regex; trilingual cooldown alert message.
- Apps Script (setup doc): per-email auto-reply dedupe + daily send cap;
applicant reply is a plain thank-you that never echoes submitted answers.
- Draft HTML welcome email (email-welcome-preview.html) for later use.
