<!--
  Matrix Decode - remocn typography primitive for HyperFrames.

  Paste the markup, CSS and script 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 invalid, and writes the result as a custom property the
  CSS consumes (or, for the target text, as the cells themselves). The timeline
  recipe below is untouched by them: it keeps staggering whatever cells are
  present.

    - text (text, default HYPERFRAMES): the word the scramble resolves into.
      One scrambling cell per character, up to 32. Also written to data-final,
      which a decode routine can read.
    - accent (green | blue | violet, default green): colour family of the cells
      and of their glow.
    - size (24 to 160 px, default 64): type size of the cells. The per-cell
      minimum width is a fixed fraction of it, so the row scales as a whole.
    - glow (none | standard | strong, default standard): halo strength behind
      the cells, from no shadow at all to a heavy bloom.

  On every default the result is identical to the original: eleven 64px green
  cells with an 18px halo.
