A visual pass over the whole suite, guided by a full screenshot review of every module.
Scenes rebuilt as real apparatus:
Twelve modules that used to show boxes and lines on a starfield now show the experiment: the photoelectric bulb on its stem with a moving-coil microammeter, the relativity train with three carriages and a station, the Bell test bench with polariser wheels and a meter that goes into the red past the classical limit, the laser cavity with its flash lamp and a beam stop that lights up at threshold, the Stern–Gerlach magnet with a knife edge and a trough, the Davisson–Germer goniometer with the Bragg planes lighting up on the crystal at the peak, the tokamak as a machine with sixteen copper coils and a glowing plasma that fades when confinement is lost, the infrared gas cell with a spectrometer board, the static-electricity room, the quantum block track with a camera on a tripod, the p-n diode wired into a circuit with an LED and an ammeter, and the hydrogen atom.
Hydrogen orbitals now go all the way to the f states (n, l, m as sliders up to 4f), with an optional translucent isosurface and a section plane, and a transition that emits a photon in the colour of its spectral line.
Electric field - charges are now polished metal spheres under scene lighting, and the field lattice is made of small 3D arrows.
Gravitational waves - the space-time sheet is a lit surface, and the merger flashes.
Across the suite:
The description card no longer runs off the screen: it caps at half the window and scrolls.
Thirty-six descriptions that had grown into walls of text were cut to a paragraph plus a few formulas.
Bloom no longer washes bright scenes out to white (fractal tree, galaxy, L-systems).
Chart axes no longer print things like 3.03e+0.
Stars in the space backgrounds are round again.
Several scenes that read as "glass" because their solids were drawn inside the glow pass are solid again (Pascal, Casimir, quantum eraser, EM wave, static electricity).
Coriolis globe is lit for the trails rather than the postcard; cloud deck is now a checkbox.
Thanks for the screenshots and reports - keep them coming.
