/* panels/visual-layers.css
 *
 * V1-UX-5: Visual Layers Bar + modal styling. Mirrors styles.css's own
 * .scope-bar / .scope-explorer-* rules token-for-token (same --panel-bg/
 * --panel-border/--card-bg/--cyan-accent/--text-secondary tokens, same
 * pill-bar + backdrop-blur-dialog structure) rather than inventing a new
 * visual language - Visual Layers and Operational Scope are sibling
 * "narrow what the workspace shows" controls, so they should look like a
 * matched pair, stacked one below the other over the Universe canvas.
 *
 * Kept in its own stylesheet (like functional-radar-workspace.css) rather
 * than appended to the already-very-large styles.css, per this codebase's
 * own precedent for a sizeable, self-contained feature's styling.
