Renders a single CMS entry as a block in isolation — no header, footer, or
preview banner. Lets us share a deep link to a single widget (e.g. the live
strommix gauge) for embedding or quick previews without exposing the rest of
the page.
- New BlockRenderer.svelte: switch over `_type` shared with ContentRows.
- Generic `getEntryBySlug(collection, slug, options)` in cms.ts so any
collection (live_strommix, deadline_banner, image, ...) is fetchable.
- Route group `(embed)/+layout@.svelte` resets the layout chain so no
Header/Footer/TopBanner inherit. `x-robots-tag: noindex`.
- Optional `?preview=<token>` for drafts. Cache: short s-maxage for live,
no-store for preview.
