* fix(studio): place GSAP step lists and duration-less tweens where GSAP plays them * refactor(studio): drop narrated comments and unnest the extend clamp * fix(studio): match keyframes in time, resolve partial step timing, start readout from prior tween * fix(studio): time step-list keyframes from the parts' last end and format * refactor(studio): trim comments to the package's comment share * fix(parsers): apply timeline defaults as GSAP does to step lists and motion paths * fix(studio): keep GSAP's ease for motion paths with keyframes and read finished tweens * refactor(studio): read a live motion path in its own step * refactor(parsers): leave step-list timing to its one owner and skip timeline defaults there * refactor(studio): move the live motion-path read into its own module * test(parsers): pin an unresolved length for a step list stretched by a variable duration * fix(studio): time keyframes linearly under an outer ease that overshoots or steps * fix(studio): time a converted expression-duration tween from its live tween, and pin no rewrite
