## Summary by cubic
Prototype visual editing mode for the preview app. Toggle the mode, pick
elements (single or multiple), and edit margin, padding, border,
background, static text, and text styles with live updates, then save
changes back to code.
- **New Features**
- Pen tool button to enable/disable visual editing in the preview and
toggle single/multi select; pro-only.
- Inline toolbar anchored to the selected element for Margin (X/Y),
Padding (X/Y), Border (width/radius/color), Background color, Edit Text
(when static), and Text Style (font size/weight/color/font family).
- Reads computed styles from the iframe and applies changes in real
time; auto-appends px; overlay updates on scroll/resize.
- Save/Discard dialog batches edits and writes Tailwind classes to
source files via IPC; uses AST/recast to update className and text,
replacing conflicting classes by prefix; supports multiple components.
- New visual editor worker to get/apply styles and enable inline text
editing via postMessage; selector client updated for coordinates
streaming and highlight/deselect.
- Proxy injects the visual editor client; new atoms track selected
component, coordinates, and pending changes; component analysis flags
dynamic styling and static text.
- Uses runtimeId to correctly target and edit duplicate components.
- **Dependencies**
- Added @babel/parser for AST-based text updates.
- Added recast for safer code transformations.

> [!NOTE]
> Broaden injection to extensionless and .html routes, gate by
Content-Type, and conditionally strip caching/compression headers only
when injecting.
>
> - **Proxy HTML injection**:
> - Update `needsInjection(pathname)` to inject for routes without
extensions and `.html` files (e.g., `/`, `/foo`, `/foo/bar`, `*.html`).
> - Only request uncompressed content and remove `if-none-match` when
`needsInjection(target.pathname)` is true.
> - During upstream response, inject only if `Content-Type` includes
`text/html`; otherwise pass through without modification.
