/* NDS V-Belt Selector v1.1.0 - scoped stylesheet
 * v1.1.0 changes:
 *   - Rebalanced guidance panel for guidance-only first paint (no preview list).
 *   - Removed obsolete nds-preview-hint / INITIAL_PREVIEW_LIMIT rules.
 *   - Kept restrained badge colors (no bright red backgrounds).
 *
 * All selectors prefixed with .nds-vbelt-selector (no global bleed).
