Subject: [PATCH] fix(16.2): WR-05 keep only view-safe attributes in the editor
 schema

captureAttributes and renderCaptured dropped only on* names, so id,
name, style, srcset, background and the like from stored HTML were
rendered by ProseMirror into the live admin DOM (DOM clobbering of
document.querySelector, fixed-position overlays, remote loads). htmlAttrs
now keeps an allowlist: class, title, alt, width, height, colspan,
rowspan, start, rel, target and data-*; href and src stay with the link
and image nodes. Other attributes are dropped from a block once it is
edited; untouched documents and untouched blocks keep their bytes.

 The element follows the admin field type element contract: the `value` property holds the HTML string; the attributes are `field-name`, `record-id`, `locale`, `ui-locale`, `options`, `disabled` and `invalid`; a bubbling `summer-change` event with `detail.value` fires on user edits only. It styles itself only through the admin `--c-*` variables, in `blogeditor.css` under its tag (TipTap's injected stylesheet is off), and never receives or sends credentials.
 
-- **Untouched values.** The element returns the exact string it was given until the user edits; an untouched imported post is saved byte for byte. Setting `value` to the string it currently returns is a no-op. After an edit, top-level blocks that are still equal to the loaded ones keep their original bytes, so editing one paragraph changes only that paragraph. Markup the schema does not model (`footer`, `section`, `aside`, `header`, `nav`, `details`, `style`, `div` and similar blocks, and a `figure` that is not an image with an optional caption) becomes a raw HTML card that shows its source as text and is written back verbatim. Unmodelled attributes on paragraphs, headings, lists, blockquotes, tables, cells, images and links, and `span` elements with attributes, survive an edit; event handler attributes (`on*`) are never kept.

On paragraphs, headings, lists, blockquotes, tables, cells, images and links, and on `span` elements, the view-safe unmodelled attributes survive an edit of their block: `class`, `title`, `alt`, `width`, `height`, `colspan`, `rowspan`, `start`, `rel`, `target` and `data-*` (`href` and `src` are kept by the link and image nodes, which check them). Every other attribute, such as `id`, `name`, `style`, `srcset`, `form`, `contenteditable`, `popover`, `itemprop` or an event handler (`on*`), is never rendered into the admin page and is dropped from a block once that block is edited; a `span` left with none of the kept attributes is dropped and its text kept. Untouched documents and untouched blocks keep every stored attribute.
 - **Embeds.** The embed button takes a YouTube URL (`youtube.com/watch?v=`, `youtu.be/`, `youtube.com/shorts/`, `youtube.com/embed/`) and stores exactly `<figure data-embed="youtube" data-id="ID"></figure>`, where `ID` matches `^[A-Za-z0-9_-]{11}$`. The admin shows a card and never an iframe; the site layer expands the placeholder. Another provider is one entry in `EMBED_PROVIDERS` (`embed.ts`) and one in the layer.
 - **Preview.** The Preview button (`Podgląd` for `ui-locale` `pl`) is off by default, belongs to each element on its own and shows its state through `aria-pressed`. It splits the editor 50/50; when the element is narrower than about 720px, the pane wraps below the editor. The pane renders the current value from the WYSIWYG or Source tab 300 ms (`PREVIEW_DEBOUNCE_MS` in `preview.ts`) after the last change, and each update reloads the frame. The frame is an `<iframe srcdoc>` with an empty `sandbox` attribute, so no scripts run and its origin is opaque. It has `referrerpolicy="no-referrer"` and a Content-Security-Policy meta (`PREVIEW_CSP`) that allows only inline styles and images. The preview copy leaves out `script`, `iframe`, `frame`, `frameset`, `object`, `embed`, `meta`, `base` and `link` elements and event handler attributes. YouTube placeholders show as thumbnail cards loaded from img.youtube.com, never as a player; these and the post's own images are the only network traffic the pane makes. The styling is post-body typography, with the `--c-*` values read from the element at render time or neutral defaults. Previewing never fires `summer-change` and never changes the value, so an untouched post is still saved byte for byte.
 - **Links.** The editor creates and keeps links only to `http`, `https`, `mailto` and relative URLs (`isPolicyUrl` in `extensions.ts`), the schemes both sanitizer policies keep; the scheme is read after removing control characters and spaces. A created link has `href` only; stored links keep their own `target` and `rel`, which the server strips on an edited save.
