Shield Block Part 1

Add this game-feel effect to my 2D game: Shield Block — Spark Burst.

Reference scene (context only — map it onto my own characters and sizes):
Side-view pixel art on a dusk ground. The hero is 12×13 art pixels drawn at 7px (84×91px); all sizes are screen px at that scale, so scale them to your sprite size. The hero stands on the left facing right and holds a kite shield (9×11 art pixels at 6px, 54×66px) centered 58px right of and 46px above its feet. A slime (16×12 art pixels, 112×84px) hops in from about 220px to the right. The scene repeats every 1.0s with the block at t=0. From −0.4s to 0 the slime hops in (x linear, 52px arc, stretched 90% wide / 112% tall for the first 0.1s) and touches the shield's right edge at t=0. From 0 to 0.35s it hops back home (easeOutCubic 1 − (1 − x)³, 34px arc, landing squash 112% / 88%), and from 0.5s to 0.6s it crouches to 114% / 86% before the next hop. The contact point is the shield's right edge at the shield's center height. Three hearts sit in the top-left HUD and never drop, because every hit is blocked. Play the effect below on every block.

The effect:
Throw sparks off the shield at t=0. For the first 0.08s, draw a white 4-point star at the contact point (two crossing bars, arm length shrinking from 46px to 24px, bar thickness 24% of the arm). …

The rest of this prompt — exact sizes, easing, colors and particle counts — and full prompts 2–6 are in the pack.
