-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.

-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.
