+URLs (once deployed to Hostinger):
+- Gate: `https://atomaste.ca/decks/gigabit-optique-fullum-cdr/enter.html`
+- Deck: `https://atomaste.ca/decks/gigabit-optique-fullum-cdr/`

+## Security note
+`enter.html` is a lightweight client-side code gate (not strong security). Use for "share link + code" only.
+
+## To customize
+- Edit the access code in `enter.html` (`const CODE = ...`). Current: `stratosphere`.
+- Replace placeholders in `index.html`.
+- Add images/plots under `assets/` and reference with `./assets/...`.
+
+## PDF export
+Open the deck and print to PDF (browser print) or use Reveal's built-in PDF mode.
