RGB Glitch Text

<!--
  RGB Glitch Text - 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 unrecognised, and writes the result as a custom property
  the CSS above consumes. The timeline recipe below is untouched by them: it
  keeps driving one red offset and one cyan offset, and intensity decides how
  far those offsets actually carry.

    - text (any short word, default "GLITCH"): the word set on all three
      stacked copies at once, so they stay in register.
    - intensity (subtle | standard | extreme, default standard): scales the
      driven offsets, from a hairline fringe to a hard tear. Both offsets are
      zero at rest, so this one only shows once the timeline runs.
    - tone (ink | paper | accent, default ink): colour of the solid copy the
      red and cyan ghosts split away from. ink is near-black for light frames,
      paper near-white for dark ones, accent rides --brand.

  On every default the result is identical to the original: near-black GLITCH
  with red and cyan copies tearing 8px either way.
