      // react-hooks v7 introduces several new rules driven by the React
      // Compiler. The migration uses several legitimate patterns those
      // rules flag (initial-fetch in useEffect, dirty-check derived
      // state, `Date.now()` inside derive helpers, inline arrow event
      // handlers, in-place mutation of imported Outbound class
      // instances in the OutboundFormModal). We're not running the
      // compiler, so the memoization-preservation warnings have no
      // effect on runtime — turning them off until the codebase
      // stabilises.
