- - Toolbox button toggles the ENTIRE right-hand column via body.toolboxClosed
- - Fix toolbox button positioning (no overlap, consistent with header container)

- Binary page styles (keeps the last-working simulator markup + binary.js).
-
- Goals:
- - Do NOT change any IDs/classes expected by src/scripts/binary.js
- - Toolbox button toggles the ENTIRE right-hand column via body.toolboxClosed
- - Fix toolbox button positioning (no overlap, consistent with header container)
- - Fix spacing/consistency of cards + buttons
- - Keep binary readout wrapping/bit-width behaviour from JS (\n in output)
