The ring hung off the node itself, and `inset` on an absolute child
resolves against the padding box — so on the brain's thick status ring it
landed inside the outer edge and painted over the status the ring carries.
Both node shapes now hang it off a border-less wrapper, where the same
offsets clear the rim whatever border the node draws (measured: 4px on all
four sides, on a 1px card border and a 7px neuron ring alike).
The shape is a conic-gradient arc masked to the padding band, running one
lap in `--duration-pulse` and going out on the way past.
Note: BrainNode.tsx also carries an unrelated in-flight change from a
concurrent session (the `seen` ref gating the pulse on a real emit); the
two could not be separated in one file.
