/**
 * Canonical inventory of the Live overlay's UI surfaces: one entry per piece of
 * chrome Live mounts on the user's page, with the element ids that make it up.
 *
 * Single source of truth, consumed by:
 *   - skill/scripts/live/browser-script-parts.mjs — serializes this into
 *     window.__IMPECCABLE_LIVE_UI_SURFACES__ in the /live.js prelude.
 *   - skill/scripts/live-browser.js — publishes it on
 *     window.__IMPECCABLE_LIVE_CHROME_CORE__ for adapters and E2E probes. That
 *     file is served raw and injected as a classic <script>, so it cannot
 *     import this module at runtime; it reads the injected global instead, the
 *     same path live/vocabulary.mjs already takes for the command palette.
 *   - the private impeccable-site repo — site/components/LiveUiGallery.astro
 *     and tests/live-ui-lab.test.mjs import LIVE_UI_SURFACES at build time and
 *     fail the site build when the Live UI lab has no snapshot for a surface
 *     defined here. That guard only guards if it reads this list rather than a
 *     copy the site keeps, so this module must stay importable from Node.
 *     Renaming a key or the module is a breaking change for that build; the
 *     list was briefly inlined into live-browser.js and the site had to parse
 *     it back out with a regex.
 *
 * Add a surface here and both the browser bundle and the site lab follow.
