Not a seal — a transcriber. Two rest states bridged by one carrier: matter at the rim (elemental), stored colour at the core (grounded), and the photon (ephemeral) the only thing that moves between them. The seams are not joins; they are transductions — the points where a bit changes what it is made of. Write: matter → light → stored colour. Read: stored colour → light → matter, out of the box.
| write → | electron (Cu/Si, momentum, valence) |
| e|p | exchanged to a photon (emission) |
| p|g | written as RGB wavelength, smeared into the store |
| read → | core emits its stored colour |
| g|p | exchanged back to a photon |
| p|e | photon touching electron — bit lands, out of box |
