Side B refactors entity rendering around reusable `entity_section`/`entity_panel` components, replaces duplicate `id` attributes with per-item `data-entity-section` selectors, and updates SSE morphing to target the correct entity via `entity_section_selector`, which is a structural correctness improvement. Side A improves the CLI panel UI by grouping commands, adding click-to-copy rows, and asserting JS-safe command strings, but those changes are primarily presentation and defensive checks rather than a broader architectural fix.
