-- **Reiasu** — original author and maintainer
+Some of the particle math uses rhodonea curves and Lissajous figures.
+Dragon respawn timing is based on vanilla's `DragonRespawnAnimation`.
 
-## Algorithms & Inspirations
-
-- **Rhodonea (rose) curves** — parametric polar curves `r = cos(kθ)` used in
-  center particle patterns (`ClientCenterEmitter`).
-- **Lissajous figures** — `x = A sin(at + δ), y = B sin(bt)` used for
-  oscillating particle trails.
-- **Ender Dragon respawn sequence** — timing constants derived from vanilla
-  Minecraft's `DragonRespawnAnimation` state machine (Mojang Studios).
