// Panel-orchestrator port block (#2030).
//
// One constant (`DEFAULT_PANEL_BRIDGE_PORT` in panel-launcher.ts) is the bridge.
// Everything else is derived from it through `panelPortBlock` so a test can pin
// the map and a future default change cannot leave +1..+4 arithmetic behind.
//
// The new default COUNTS DOWN from 9199: counting up would put the panel HTTP-MCP
// on 9200 (Elasticsearch / IANA wap-wsp). 9180-era sessions keep the historical
// +1..+4 block so a phone paired on 9182 and a panel MCP on 9181 still work
// across the migration.
