/* Vendored LView slot indices from `@angular/core`. The runtime represents
 * each LView as a flat array; these constants name the structural slots
 * before the per-template slots start at HEADER_OFFSET.
 *
 * Source: `node_modules/@angular/core/fesm2022/_effect-chunk2.mjs`
 * (search for `const HOST = 0;`). These are NOT exported and Angular keeps
 * them tightly held — but they have not shifted since the v9 ivy rewrite,
 * so the maintenance cost is verifying once per Angular minor that
 *   `_effect-chunk2.mjs:HOST === 0` etc. still holds.
 *
 * If Angular reorders these, our LView traversal returns wrong slots
 * (e.g. reading PARENT might yield CONTEXT). Symptom: per-component
 * remount throws or silently swaps the wrong subtree. Verify at the
 * top of `angularRemount.ts` via shape checks before doing anything
 * destructive. */
