/**
 * Standalone format renderers for custom UI iframes.
 *
 * Served as `/api/photon-renderers.js` and lazy-loaded by `photon.render()`.
 * Pure vanilla JS — no framework dependencies. Mirrors the auto UI's
 * @format rendering but as imperative functions.
 *
 * Usage inside custom UI:
 *   photon.render(container, data, 'chart:bar')
 *   photon.render(container, data, 'table')
 *   photon.render(container, data, 'gauge', { min: 0, max: 100 })
