docs: allow brand ring as location in choice→consequence rule

[detail-app]

Summary

§7.2 of design-console-ux.md ("Choice→consequence editors") still said
"a risky option must never wear the safe hue" after commit 807ae84 switched
the choice-card selection ring from ring-white/40 to ring-brand-500/50.
That rule now literally contradicts the implementation: the risky self-approval
option in policies_live.ex approval-requirements choice cards wears the
emerald brand ring when selected. Clarified that the brand ring marks the active
input as location (not a verdict); green fills and status treatments remain
forbidden — matching the model the same commit already applied to §2 of this
file and to design-complex-editors-follow-decision-order.md.
