Physics Toast: Dynamic Island-inspired Morphing Toast in Pure JS

Physics Toast: a vanilla JavaScript library that renders Dynamic Island-style toast notifications with a real damped spring physics engine.

Key highlights:

• ~20 KB total, zero dependencies
• Real spring simulation (F = -kx - cv) — not CSS keyframes
• SVG gooey morph effect via feGaussianBlur + feColorMatrix
• 6 toast types: success, error, warning, info, promise, action
• 6 screen positions, swipe to dismiss, auto expand/collapse
• Drop-in with two tags — works in any HTML page, no React needed

Great fit for static sites, admin panels, browser extensions, or any project where pulling in a full React runtime is not an option.
