A11y checkers (axe-core / jsx-a11y) flag the boolean form because the
ARIA spec defines aria-checked as the enum "true" | "false" | "mixed",
not a boolean. React serialized the boolean to the right wire value at
runtime, but the inspection layer keys off the JSX expression's static
type. Switching to the explicit ternary silences both.
