/* lipinski — tool CSS, retired in Chunk 4a.
   Every rule this file held is replaced by the Chunk 1 design system:
   .example-box, .example-row, .field-err (the JS now creates
   .field-error, the Chunk 1 class), .data-toggle (the data table now
   uses the shared Show data button), .lip-tabs / .mw-tab (Chunk 1
   .tabs), .why-box (now a plain .card) and .unit-toggle / .unit-btn /
   .check (dead rules copied in by migrate.py — this tool never used
   them). The .btn-row, .status, .export-bar and .table-wrap helpers
   stay in assets/tool-base.css. This file is kept (empty) so build.py
   still finds the per-tool stylesheet the manifest expects. */
