/**
 * Phase detection, font fallback, and shorthand normalization helpers
 * shared by the engine entry point and the per-phase wrapper modules.
 *
 * These were extracted from `engine.ts` during M3.b so that the
 * `composePhases` runner could consume them without creating a cycle
 * (engine.ts → phase wrapper → engine.ts).
 *
 * No behavior changes from the engine.ts originals.
