/**
 * Imports a module for its style side effects, defeating the module cache
 * when — and only when — the result would otherwise be wrong.
 *
 * Styles register themselves while their module evaluates, and a module
 * evaluates once per specifier. Two things therefore have to reach the
 * specifier: the file's mtime, so an edit re-registers the module's rules
 * during a watch rebuild; and the registry generation, so a reset re-runs
 * every module instead of leaving the registry permanently empty.
