Miguel Angel Simon Sierra 35231e964d fix(registry): connector geometry, family accent, and demo legibility 
Found by stepping through motion contact sheets rather than single frames.

- hw-pipeline: arrowheads were two asymmetric barbs (l -30 -14 / l -26 18)
  fixed to horizontal, so they detached from a curve that arrives on a
  descending tangent. Barbs now derive from the quadratic's end tangent
  (end - control) with symmetric length and spread.
- hw-pipeline, hw-scribble-transition, hw-callout-circle: the family carried
  two accents — #ffb020 in hw-frame/hw-title/hw-underline and #6d6dff here.
  Unified on the warm marker accent; the blue read as a default UI colour.
- hw-callout-circle: the scribble hatch rendered as stacked bars over the
  labelled subject. More rows so the zigzag reads as a scribble, lighter
  weight and alpha so it sits behind the label.
- yt-camera-move: the stage grid was too faint to reveal the move, so the
  preview of a camera-move component looked static. Stronger grid; zoom,
  slide and tilt now read.

Demos resynced from source — demo.html is a plate-swapped copy, so a source
fix does not reach the catalog preview until it is regenerated.
