   =========================================================
   Shared control panel components used across tool pages.

   Includes:
     Section wrapper  — .tool-section, .tool-section-label
     Dropdown card    — .tool-dropdown-* component family

   Loaded by:
     palette-builder.php
     typography-builder.php

   Tool pages override padding, min-width, and list
   direction for their specific context — see each tool's
   CSS file for those overrides.
