/**
 * Ledgerline: live cost and session intelligence for Hermes Desktop.
 *
 * One file, loaded uncompiled by the desktop's disk plugin door. Three rules
 * keep it loadable on every desktop build:
 *
 * 1. Import the SDK as a namespace. The runtime shim exports
 *    `export const { a, b } = m`, so a named import of a member an older SDK
 *    lacks is a link-time SyntaxError for the whole file. Newer members are
 *    read off `sdk.*` behind a feature check instead.
 * 2. Everything between the pure markers has no imports and receives its
 *    dependencies as arguments (`host`, `bridge`, `sdk`). Tests load that
 *    slice under node and pass fakes. UI and registration live below it.
 * 3. No hardcoded colours, no polling faster than 30 s, no writes to the
 *    gateway host outside Hermes' own commands.
 *
 * Module map:
 *   capabilities  what this desktop / gateway can do, probed once
 *   data          rpc / coreRest / cli adapters with typed errors, plus the
 *                 session reads and analysis rungs built on them
 *   sessions      pure shaping: normalize rows, filter, sort, format
 *   true cost     parent plus children, receipt lines, live estimate
 *   ui            React components built from the SDK kit
 *   register      contributions (page, nav, palette, keybind, statusbar chip)
