Labelled layouts for both halves, and the overview redrawn from the real
shapes rather than a placeholder ergo core. The 36/39 asymmetry means the two
halves are separate board designs, not one file mirrored - README and BOM
updated to match.
100 of the 104 positions now have a physical key; only Insert, PrtSc, ScrLk
and Pause need a layer.

Six by five. Arrows on the outer column, PgUp/PgDn beside them, no Num key.
The scroll wheel is dropped - no good physical implementation - which also
removes the pointing-device path from the firmware entirely, frees a USB
endpoint, and retires the detentless-EC11 sourcing risk. The freed 2u at the
top takes a single volume encoder with room for a full-size knob.
BOM: diodes and sockets 26 -> 25, encoders 2 -> 1.

Two mirrored halves plus a numpad that carries the USB hub. Captures the
architecture decisions and the reasoning behind them: CH32L103 with an
STM32F103 pin-compatible escape hatch, split protocol tunnelled over USB-C
SBU through the numpad, hotswap sockets bottom-side, and why crystal-less
USB was ruled out across the whole WCH catalogue.
No boards ordered, no firmware written. Layout still undesigned.
