Design thesis. Same structural grammar — phase strip, day bar, challenge list, profile — five different material worlds.
Neuron = blueprint + neural net. CyberHub = terminal + neon green.
Axiom = graph-paper notebook, ink-green curves, pen-on-paper sketches.
Turing = code editor, amber on charcoal, file tabs and gutter line numbers.
Sketch = loose drafting sketchbook, oxblood marks on warm paper, Caveat handwriting.
Each of the three active courses ships with a sandbox as the center of gravity: a notebook for Axiom, a code editor for Turing, a CAD workbench for Sketch — where challenges live, hints are served, and an AI review button sits one click away.
