changed the title
shadow-xs, and keyline border width.
Introduce a smaller box shadow between the existing default and sm sizes, and expose it through the shadow utilities.
Shadow color and opacity utilities now compose through local --sc/--so
variables (like --bc for border-color) instead of setting --shadow-color
and --shadow-opacity directly, so .shadow-{color} and .shadow-opacity-*
no longer leak into nested .shadow-* descendants. The $shadows map
(scss/_config.scss) reads var(--sc, var(--shadow-color)) and
var(--so, 1), keeping --shadow-color/--shadow-strength as the
cascading global defaults. Removes the now-unused at-property utility
key since no utility needs the cascading opt-out anymore.
Updates the shadows docs with a nested-elements example and callout,
and adds a migration guide entry.

Introduces a themeable, layered shadow system plus a
.5pxkeyline border width, and wires them through components and docs.775aea8ef): reworks--box-shadow-*tokens into multi-layer shadows built from three new tokens:--shadow-color— retints every shadow (drives.shadow-{color}utilities, e.g..shadow-primary)--shadow-opacity— dims/boosts shadows (drives.shadow-opacity-*)--shadow-strength— deepens all shadows, bumped automatically in dark modebase * strength * opacityviaoklch(from …), and utilities emit the literal layered expressions so the nested vars resolve on the element..shadow-xlsize; applied across_dialog,_drawer, and_menu.555aa6c31): adds--border-width-keyline: .5pxand a keyline border width, with docs examples on header menus + search input..shadow-xs(001ee7ad8, cherry-picked from9ec72b67e): adds a themed--box-shadow-xstoken (single subtle layer, consistent with the layered system) and.shadow-xsutility. Reconciled with the layered token style during cherry-pick..shadow-xl/.shadow-xs, and keyline usage.Notes
.shadow-xscommit originally used the old flatrgb()shadow values; it was adapted here to the new layeredoklch()token format so it stays consistent with the rest of the system.npm run dist/css-lint, so thedist/artifacts are not regenerated in this branch. Recommend running the full build before merge.
