Nasty Jablocks/Resets in Smash 4 #4

Compilation of Smash 4 jablocks and resets from YEETSmash. The focus is on kill setups and mixup sequences — positions where a single mistake in spacing or shield timing opens into an unavoidable combo string or stage spike. Without character names or player tags in the available data, the value sits in isolating the frame windows where these confirms become true blockstrings, and identifying which ledge positions make the reset trigger. Fourth entry in the series; earlier volumes establish the foundational spacing checks.
