The check added last commit derived its elevated set from the sheets that already rebind, which cannot catch the omission it targets: such a set only confirms what someone already remembered, and a surface nobody has rebound yet defines itself as unelevated. Review found the case that proves it — TodoPanel scrolls in .list on a --dsw-specific-tip card, the same dark rung as the menu surface, unrebound and with the derived check green. Resolves the set from the palette's own dark elevation ladder instead: the surface tokens whose dark value lands on bg-layer-2 or bg-layer-3, which is the step the l1/l2 split encodes. A new palette token on an elevated rung is in scope the moment it is defined. Scope is by token family rather than geometry: only --dsw-alias-bg-* and --dsw-specific-* name a surface. The button, interactive, and markdown families reach the same rungs while naming a control or an inline span that no scroll container renders a bar against, and shape cannot separate them since a floating button carries a radius, a shadow, and a fixed size — ChatView's .toBottom pill was the false positive that showed this. Adds the missing TodoPanel rebind. Mutation-checked all four rebinds in turn: each is named with its surface. The palette anchoring has its own control — narrowing the family pattern turns it red on --dsw-specific-menu.

Theme plugin: ThemeService over the --dsw-* token base stylesheets (static scale + alias semantic layers). The service owns the theme preference (light/dark/system, persisted under dsh.theme), resolves system through prefers-color-scheme, and publishes immutable ThemeSnapshots on the theme/change event; it never touches the DOM — ui-layout's presenter applies the resolved snapshot (html { color-scheme }, body[data-ds-dark-theme], and inline alias tokens). Contract: api-contracts v3 §8.
src/styles/ holds five sheets, all imported by the web shell's base.css: base.css, design-platform.css, scrollbar.css, gradient-shadow-text.css, and shiki.css. scrollbar.css is the sole consumer of the --dsw-alias-scrollbar-* tokens and must follow design-platform.css, which declares them.
Scrollbar rebinding contract: scrollbar.css binds --dsh-scrollbar-thumb and --dsh-scrollbar-thumb-hover on body to the l1 (base-surface) tokens, and both rendering paths read that pair. An elevated surface (menu, popover, dialog) sets --dsh-scrollbar-thumb: var(--dsw-alias-scrollbar-bg-l2) and --dsh-scrollbar-thumb-hover: var(--dsw-alias-scrollbar-hover-l2) on its own container; one rebind retints whichever path the engine took.
The two paths are mutually exclusive by construction. scrollbar-width/scrollbar-color sit inside @supports not selector(::-webkit-scrollbar) because a non-auto value of either makes Chromium and Safari discard every ::-webkit-scrollbar* rule for that element, ::-webkit-scrollbar-thumb:hover included — declaring both unconditionally leaves --dsh-scrollbar-thumb-hover with no rendering anywhere. Firefox therefore takes the standard properties and WebKit-based engines take the pseudo-elements, so the hover token only ever renders through the pseudo-element path. Reasoning and the measured computed values: the scrollbar Agent Note.
Model Experience
None, as the theme service manages a browser preference; nothing here reaches a model request.
KV Cache effect
None; this package neither assembles nor sends a provider request.
Known Limitations and Deferred Work
- Third-party themes are a surface, not a product — registering one means overriding same-named alias variables; no validation exists that an override set is complete.
- The token sheets are the sole color authority — values absent from cssdesign (for example the design's #4176E6 tab blue) are deliberately not appended; the nearest semantic token wins (arbitrated 2026-07-22).
