Extend the left-hand aircraft sidebar — add a new sort chip, a new list-filter chip, a new per-row metric, or a new header/status element. Covers the fingerprint-cache invariant that makes every per-row change subtle (miss a field and the row stops re-rendering when it changes), the lastX cached-text pattern for header elements, delegated event wiring, and the escapeHtml discipline for user-sourced strings. Use when the user asks for "sort by X", "add a MIL/watched/whatever filter chip", "show field Y in each row", or "add a status pill to the sidebar". Don't use for the aircraft detail panel (that's `detail-panel-section`), dialogs, or the map overlays.

The sidebar on the left is rebuilt from renderSidebar(snap) on every 1 Hz snapshot tick, but rows themselves are DOM-diffed by fingerprint — each row's HTML is cached keyed on an icao and a |-joined string of every value that affects the rendered markup. If the fingerprint matches the cached entry, the cached Element is reused verbatim; otherwise the row re-renders once and goes back in the cache. That design keeps scrolling through a busy sidebar cheap and prevents focus / selection flicker, and it is the single most important constraint for anyone adding a new per-row field: if your new…
