- Introduce collapsible right-hand toolbox for the binary simulator - Pin toolbox to the right edge with responsive fallback on smaller screens - Rework tools and bit-width controls into a shared side layout - Adjust control sizing, spacing, and visual hierarchy for clarity Notes: - Toolbox collapse is functional but requires refinement - Tools and Bit Width should be merged into a single module/card - Collapsed state does not yet fully hide the panel or re-centre content Signed-off-by: Alexander Lyall <alex@adcm.uk>
