/* Annotator search-and-claim sidebar.
   Left-edge toggle (memos owns the right edge).

   Consistency: this consumes the memos design system tokens directly
   (loaded first in base_template_v2.html) so the two sidebars can never
   drift. Literal fallbacks keep this file self-contained if load order
   ever changes. Vanilla CSS, no deps, no build step. */
