- USBLabelBatch.vue: recolor controls/selection/cell borders to the app CSS
variables (was hardcoded #667eea/#28a745/#dc3545) and add
`print-color-adjust: exact` so barcodes print even with "Background graphics"
off. (Barcodes render as vector SVG, so no canvas->img change needed.)
- ADR-004: document the resolved migration strategy - single core Alembic chain
(`flask db upgrade`), bundled plugin schema folded into core (7c04), resolving
the Phase 7B per-plugin-chain conflict footgun. External plugins may still
ship their own chains.
