 * Trailing-edge debounce and leading-plus-trailing throttle.

 * Ported from maker-ds `form-inputs/combobox-shared/debounce.ts`, for the reason its
 * own header gives: pulling `lodash-es` in for two functions would drag a transitive
 * install into every consumer of this package.
 *
 * Not exported from the package. `scripts/generate-exports.mjs` only publishes a
 * directory with an `index.ts`, and `internal/` deliberately has none — these exist to
 * serve the combobox's async modes, and promoting them to public API is a separate
 * decision from needing them here.
