/**
 * @fileoverview Visualization control toolbar + function-level projector.
 *
 * A render helper (registers no view), extracted from `view-graph.ts` to keep
 * that emitter under the file-length budget — and, like `graph-stylesheet.ts`,
 * deliberately named out of the `view-*` namespace so it stays clear of the
 * views-disjoint architecture rule. Emits two browser functions plus a tiny
 * helper as a JS string; the main emitter interpolates it into its `<script>`
 * body, so they share one runtime scope with the view's state vars
 * (`gvLevel`, `gvSelectedPackage`, …) and `gvRenderGraph`.
 *
 *  - `gvRenderControls(host, catalog, indexes)` — the self-contained Level /
 *    Scope / Package / Kind / Edges control bar. Package + Kind are disabled at
 *    package level (they only apply at function level). Every change re-renders
 *    the graph in place via `gvRenderGraph`.
 *  - `gvBuildFunctionElements(indexes, pkg, includeTests, kinds, crossPackage)`
 *    — projects ONE package's function call graph client-side from the catalog
 *    indexes (the package→package view-model blob can't express it).
 *  - `gvAddOptions(sel, pairs, current)` — small `<select>` option builder.
 *
 * Free identifiers (supplied by earlier prelude emitters / the host template):
 * `el`, `pkgOf`, `displayName`, `resolveCalleeOcc`, `packagesInCatalog`,
 * `KIND_LIST`, `gvRenderGraph`, `GV_LAYOUTS`, `gvRunLayout`, `gvSccHighlight`,
 * `gvApplySccHighlight`, and the `gv*` control-state vars.
