    //   exactOptionalPropertyTypes — genuinely valuable (it distinguishes "absent" from "present and
    //     undefined", which is exactly the class of bug that produced several defects in the WebView
    //     bridge). Measured at 182 errors across 7 packages alone, so it is a migration of its own
    //     rather than a flag flip. Worth scheduling.
    //
    //   erasableSyntaxOnly — rejects `enum`, and the LogLevel/Severity enums in @bugsee/protocol are
    //     part of the wire contract. Converting them to const objects is churn with no safety gain.
    //
    //   noPropertyAccessFromIndexSignature — 65 errors, and it buys style (obj['k'] over obj.k) rather
    //     than safety, since noUncheckedIndexedAccess already forces the undefined check that matters.
