eslint.config.js

// Flat ESLint config (ESLint v9+). Migrated 2026-04-16 to close the gap Raze/Quinn-v2
// surfaced during sprint retro-eval. Prior state: project had ESLint v9 and eslint-config-next
// installed but no config file, so `npx eslint .` failed with "couldn't find an
// eslint.config.(js|mjs|cjs) file" — the lint gate was non-functional for weeks.
