 Place your source `.html` or `.htm` files here or in subfolders. Importing a file stores a new version in the Access database. Images are copied into that version, so later edits to source files do not change an imported snapshot. Keep private campaign artwork under `templates/local/`, which Git ignores.
 
-The current importer accepts **well-formed HTML written as XML**. Close every tag and quote every attribute, including `<img ... />` and `<br />`. It accepts basic text, links, tables, and constrained inline `style` attributes. It rejects scripts, forms, external stylesheets, event handlers, remote images, SVG, and CSS image URLs. Image paths must be relative to the HTML file's folder and use PNG, JPEG, or GIF.
