Resize: proportionally scale all GSAP animation positions and durations to fit the new clip duration via scalePositionsInScript. This preserves clip-relative keyframe percentages — diamonds don't move during resize, nothing disappears. Modeled after After Effects Time Stretch behavior. Drag: shift all GSAP positions by the time delta (unchanged from before). Diamond rendering: - Clamp diamonds at 0%/100% so they stay fully visible at clip edges - Filter out-of-range keyframes using predicted percentages during resize - Clamp connection lines to clip boundaries - PropertyRows: same edge clamping for SVG diamonds Parser: scalePositionsInScript (proportional position + duration scaling), shiftPositionsInScript (rigid shift), scale-positions + shift-positions mutation types, 5 shift tests passing.
