Coma & Brain Death module; ototoxicity, EABR, and functional-loss subsections
content
New topic module 'ABR in Coma & Brain Death' covering prognostic grading, serial monitoring, the wave I caveat, and ABR's ancillary role in brain death determination. New subsections fold in three further entities assessable with ABR: ototoxicity monitoring on the SNHL page, cochlear nerve deficiency and electrically-evoked ABR (EABR) on the ANSD page, and functional (non-organic) hearing loss on the Threshold ABR page.

Threshold ABR module and clinical cases
content
Threshold ABR module covering paediatric audiology technique, frequency-specific tone-burst stimuli, latency-intensity function pattern recognition, and dB nHL to dB HL correction. Eight hand-authored clinical cases at /cases spanning cochlear loss, conductive, schwannoma (both large and small intracanalicular), ANSD, MS, brainstem infarct, and CAPD.

Next.js 16.2.6, React 19.2.4, TypeScript strict with noUncheckedIndexedAccess, ESLint 9 flat config without FlatCompat, App Router only, static export only. Pure-math layer separated from React: bera.ts, srs.ts, streak.ts, archetypes.ts, search.ts, latency-intensity.ts. SSR-safe localStorage via useSyncExternalStore from day one.
