Stick the page actions bar to the top of the viewport
Make the page header actions (the "On this page" toggle and the assistant / page actions) stick to the top of the viewport on non-mobile viewports, so they stay reachable while scrolling long pages such as API references (RND-11139). - PageHeader: render the actions as a sibling of `<header>` (a direct child of the scrolling `<main>`) so its sticky containing block is the full page rather than the short header, which is why it scrolled away before. It pins padded just below the site header using the same server-default + client CSS-var pattern as the table of contents, and drops below the "On this page" panel when that is expanded as an overlay so it doesn't show on top of it. - OpenAPI: shift the sticky code-sample preview down so it clears the newly-sticky bar, and leave a small gap at the bottom of the viewport. - Button: keep secondary buttons' background in the flat depth style instead of making them transparent, so the sticky actions stay visible over the content they scroll past.

-A near-white tint color (e.g. a warm `#F5F3EF`) is now taken as the exact page background, mirroring the existing behavior for near-black tints. The tint's exact lightness, hue and chroma are preserved, and the color is anchored to whichever scale step the active theme renders as the background — so it matches exactly on `muted` (which uses the second step) as well as `clean`. This applies only to near-neutral tints that are light enough to read as a background; saturated or merely light-ish colors keep their normal accent scale. The `bold` theme is unaffected: it already uses the tint for the header and stays intentionally two-tone.

-Introduce client-side content selection (`select`): a site-wide, recency-ordered list of selected slugs, persisted in localStorage and shareable via `?select=`, applied to `<html>` before first paint so the right variant renders with no flash. All variants stay server-rendered, so pages are byte-identical for every visitor (no cache impact).
-
-Tabs now use it: switching a tab activates its slug, and every tab group offering that slug follows, across pages. Tabs no longer write to the URL fragment (`#` returns to anchors only); deep-links into a tab still activate and scroll to it.

-Fix the docs embed not applying `?theme=light`/`?theme=dark`. The theme was dropped when the embed redirected to its default tab, and the embed tabs couldn't read it because they render statically (their request headers are empty). The middleware now threads a forced embed theme through the embed route context (scoped to the embed, not the main site), so the embed tabs honor it while staying statically rendered, and the redirect forwards it to the default tab. The forced theme is also persisted to the embed's own theme storage so it is remembered across tab navigation instead of only applying while the query string is present.

-
-Comment to explain *why*, not *what* — the code already shows what it does. Keep comments short, ideally a single line. Avoid multi-line block comments that narrate mechanics a reader can follow from the code; they add noise and go stale. Reserve longer comments for genuinely non-obvious rationale: a subtle invariant, or a workaround and the reason it exists.
