When FEATURE_BITCOIN_CONNECT is on, "Connect wallet" is the primary path and the
raw Wallet Connect URI field collapses under an "Advanced — paste a connection
manually" <details> disclosure (backup, de-emphasized). When the flag is off, the
controller forces the disclosure open and hides its summary, so the URI field
shows plainly exactly as before (no behavior change). Default-zap field stays
always visible. Adds a small token-based rotating-caret style for the summary.
Still LOCAL (flag ON for testing); not pushed, not deployed.
