Shell & Micro-Frontend UX Coherence — Affordances That Are Found, Consistent, and Talk Back

One demo-prep session turned into a chain of 'I can't find / reach / trigger X' failures across Pack Runner, Enhanced Records, and Response Reviewer. Individually each was a one-line patch; together they're a verdict — the augment-it shell's affordances hide, die, or mismatch. This spec audits the whole shell + its micro-frontends through that lens and fixes the pattern, not just the instances.
