Interactive Maxwell planar interface boundary conditions for (\vec{E}/\vec{D}) and (\vec{H}/\vec{B}). Drag the incident field, change (\varepsilon_r) or (\mu_r), and watch which components stay continuous — not Snell’s-law ray optics (see OpticsLab).
- Electric screen: dielectric interface with (\vec{E}) and (\vec{D}), (\varepsilon_r) presets/sliders, adjustable free surface charge (\sigma_f), optional bound charge (\sigma_b) with polarization (\vec{P}) arrows, component overlay, field lines, protractor, and angle readouts
- Magnetic screen: same interaction grammar for (\vec{H}) and (\vec{B}) with (\mu_r) and free surface current (K_f)
- Equation strip highlighting continuous BC terms ((E_t), (D_n) or (H_t), (B_n)), switching to jump conditions when (\sigma_f) or (K_f) is nonzero
- Interface glyphs for free surface charge ((+)/(-)), bound charge (hollow (+)/(-)), and surface current (⊙/⊗)

New sims start at version: "0.0.0" in package.json. Bump only when cutting a release (for example npm version patch and a matching git tag). Keep name in kebab-case; it is separate from the SceneryStack sim identifier in src/init.ts.
