Integration detail headers rendered Disconnect in red while Connect used an unaccented chip. Use the standard primary chip for Connect and Add account, and the neutral header chip for Disconnect. The existing shared header ordering places the primary action last; the disconnect confirmation retains its destructive treatment.
Connection handlers, permission checks, and pending/disabled guards are unchanged.
Validation: cleanup review across the React, state, query, URL, comment, and EMCN passes; lint; all workspace type checks; all 62 audits; generated-artifact checks; and the block-registry check passed. Runtime and browser tests run in CI.
