/* =========================================================================
 * CZPWeb vehicle-database.css — v149.42 (Phase 1B Step 5)
 * =========================================================================
 *
 * Styles for the in-app Vehicle Database panel (Option B architecture).
 * All selectors prefixed with .vdb- to avoid collision with main app CSS.
 * Inherits theme variables from app.css (--app-bg, --app-text, etc.) so
 * the panel adapts to the active skin (Courtroom default).
 *
 * Structure:
 *   .vdb-panel                       outer container (replaces workspace view)
 *     .vdb-panel-header              top bar with title + close
 *     .vdb-main                      grid: filters | results
 *       .vdb-filters                 left sidebar with filter controls
 *       .vdb-results                 right pane with toolbar + table
 *     .vdb-modal-backdrop            overlay for detail + save modals
 *     .vdb-toast                     transient notification
 *
 * D-049 — formatting (inches, feet) is done in JS; CSS only provides
 *   monospace alignment for numeric columns and the courtroom skin's
 *   high-contrast palette.
