@@ -51,15 +51,23 @@ The Builder can export a production-ready ZIP that contains:
  - Name, Short Name, Start URL, Display (dropdown), Theme Color (HEX only)
 - Robots
  - Disallow lines (textarea). Each line becomes a `Disallow:` rule.
  - Robots Meta: `<meta name="robots" content="...">` value (e.g. `noindex, nofollow`). Empty disables the tag.
 - Google Sheets Template Mode
  - Auto: include when `form.actionUrl` is empty
  - Include: always include
  - Exclude: never include
 - Font Optimization
  - Preconnect: toggle inclusion of Google Fonts preconnect links.
  - Preload: preload & load Google Fonts stylesheet with `media="print" onload` pattern.
 - Image Options
  - Loading: `lazy` (default) or `eager` for `<img loading>`
  - Decoding: `async` (default) or `sync` for `<img decoding>`
 ### site.webmanifest and robots.txt
 - `site.webmanifest` is derived from page data; Export Options can override fields.
 - `robots.txt` defaults to a permissive header and adds `Disallow` lines from UI.
 - `meta name="robots"` can be injected via Export Options and is written in `<head>`.
 ### Asset paths and grouping
