Focus Blur Resolve

<!--
  Focus Blur Resolve - remocn typography primitive for HyperFrames.

  Paste the markup and CSS into a composition. Drive the timeline integration
  from a paused GSAP timeline so renders remain deterministic.

  Variables. The script reads each one, falls back to the declared default on
  anything missing or unrecognised, and writes the result as a custom property
  the CSS consumes. The timeline recipe below is untouched by them: it keeps
  driving one scale and one blur, and these decide how big the words are, what
  colour they resolve to, and how deep the blur they resolve from goes.

    - tone (ink | paper | accent, default ink): word colour. ink is near-black
      for light frames, paper near-white for dark ones, accent rides --brand.
    - size (compact | standard | display, default standard): type size, 40px,
      56px or 84px.
    - blur (soft | standard | heavy, default standard): scales the blur radius,
      so the pull starts as a light haze or a full smear over the same run.

  On every default the result is identical to the original: near-black 56px
  words resolving out of a 16px blur.
