Table fixes: - Add BSSID column header to match data columns - Remove vendor column from table rows (6 columns total) - Update placeholder colspan to 6 Layout fixes: - Use minmax() for right columns to allow shrinking - Add overflow handling to layout container - Add min-width: 0 to analysis panel for proper grid behavior - Add overflow-x: auto to channel chart container Channel chart fixes: - Reduce bar width from 20px to 14px - Reduce bar spacing from 4px to 2px - Reduce padding for more compact display - Use viewBox for responsive SVG scaling Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
