Setting characterDelay or lineDelay to zero still returns the default 40 ms, so callers cannot turn off the corresponding delay. Both setters already accept zero, and the typing implementation already supports it.

Preserve numeric zero before applying the existing fallback. Missing, empty or whitespace-only attributes keep their default, and reduced-motion handling is unchanged. The regression covers delay attributes, property assignments, and empty/whitespace/fractional fallbacks.

Validation: the regression first returned 40 instead of zero; all 9 Chromium tests now pass through the repository's Karma runner. The TypeScript distribution build and full ESLint check pass with the installed lockfile dependencies on Node 24. The Windows cleanup wrapper was bypassed by running the same tools directly; Firefox and WebKit were not run.
