Schema Qr

Self-contained QR code for a given URL (or the current page URL on JS-capable surfaces) — computed via the vendored QR-Code-generator library (Project Nayuki, MIT) and rendered as inline SVG, zero network calls. Optionally interactive — set is_interactive to add a text input that live-regenerates the QR client-side as the visitor types.
