Bundlers like Vite 5 that enforce strict export resolution cannot resolve 'weas/style.css' unless it is listed in the exports field.
Add AtomTooltipManager plugin that shows element symbol, atom index, and Cartesian coordinates on mouse hover over atoms. - Lazy init: DOM and events only created when enabled - Configurable via enableAtomTooltip (default: true) - Integrates with viewer state system (applyState/setState) - Tooltip state resets on re-render but DOM survives - Zero new dependencies (native DOM + Three.js Raycaster)

Hi! We've been happily using WEAS in our project for interactive crystal structure visualization — thanks for the great work!
