BlurText changelog

Reimplemented the original site behavior with real inline-block characters, independent blur filters and opacity, and main-thread 2D translation; removed the earlier top-position and pseudo-element approach.
Exposed speed as a rate multiplier, using character start rates of 0.5, 1.5, and 2 to match the original site.
Added blurred character-by-character reveal, natural text layout, replay, continuous updates, and a reduced-motion fallback.
