Micro Transitions

<!--
  Micro Transitions - transitions.dev-inspired UI motion pack for HyperFrames.

  Includes six app-transition patterns in one copy-paste snippet:
    badge pop, dropdown reveal, modal open, tab indicator, tooltip appear,
    and success check draw.

  Animate --hf-micro-progress from 0 to 1, then optionally animate
  --hf-micro-tab from 0 to 1 for the segmented control.

  Variables. The script reads each one, falls back to the declared default on
  anything missing or unrecognised, and writes either the panel wording or a
  custom property the CSS below consumes. The two progress drivers above are
  untouched by them.

    - badge (any short text, default 3): the count inside the red chip on the
      bell. Blank or non-text input falls back to the default.
    - tooltip (any short text, default Copied): wording inside the small dark
      tooltip.
    - tone (red | amber | violet, default red): colour of that badge chip, the
      one accent-carrying element in the pack. red and amber are literal alert
      conventions; violet rides the composition's own accent-2 token and falls
      back to ink when the composition declares none.
    - travel (close | standard | far, default standard): scales how far every
      panel starts from its resting place, so the whole pack drifts half as far
      or nearly twice as far into position over the same progress run. At full
      progress each panel lands in exactly the same place.

  On every default the result is identical to the original: a red 3 on the
  bell, a Copied tooltip, and panels that rise between 6px and 18px.
