Regenerate everything after a template tweak: serve the site locally (python3 -m http.server 8802), then run scripts/render-marketing.sh. All outputs land in marketing/ at 2× resolution. This page is noindexed — share the URL only with people who need it.
Email signature
Fixed 500px wide, images embedded (base64) — it can't stretch in Outlook and the logo can't detach on reply chains. Copy, then paste into the signature editor on desktop AND the mobile app so every device sends the identical block. Mobile links: WhatsApp / Telegram buttons point at the mobile number entered above. For phones: Outlook & Gmail mobile apps only accept plain-text signatures — pick mobile brief and use Copy as text.
