1 · Master template
Pick the master index.html. When this generator is opened
over HTTP from the same folder, the master is fetched automatically.
2 · Client data
The page's built-in offline vCard (used when the hosted vCard can't be fetched at tap time) keeps its phone/email from the master template; name, title, company, and website always follow this form.
3 · Signature
Sign inside the dashed guide — the pad has the same proportions as the page's signature area, and the result is always perfectly centered above the name, however you draw it. Starting a new drawing discards any uploaded file.
Subtle values look most authentic — the pad already captures natural handwriting variance.
4 · Background
5 · Generate
Live preview
The preview runs the real generated page — waves, animation, and download flow all live. (The vCard fetch itself may be blocked in some sandboxes.)
