docs: bring the README in line with what actually ships

The records bullet claimed inbound document handling — the document
vault is disabled and belongs on the roadmap, not in the feature list.
The device bullet gains Google Health and Nightscout, the check-in
bullet gains WHO-5 and the SCI, the AI bullet reflects guideline-band
interpretation and acceptable plans, and the language claim grows from
two locales to the six that ship.

 ## Highlights
 
 - **Every vital on one timeline.** Weight, blood pressure, pulse, glucose, body composition, sleep, SpO₂, respiratory rate, mood, and cycle tracking — charted with trends, moving averages, and clinical reference ranges (ESH 2023, ADA 2024), overridable with the targets your clinician set.
-- **Clinical signals, opt-in and additive.** Validated mental-wellbeing self-checks (PHQ-9, GAD-7) that sit beside mood tracking with calm crisis-resource handling, grip strength, a 0–10 pain score, waist and body measurements, and a longevity lab panel — each added through one signal registry, so a new signal wires into charts, correlations, the coach, the FHIR map, and the API at once.
-- **Records and the documents you're handed.** Structured allergies and family history (encrypted), lab values you key in or scan, and inbound documents — discharge letters and reports — read to extract the facts they state (values, codes, dates) for you to review and confirm. HealthLog transcribes what a document says; it never interprets or diagnoses from it. (Immunization records are deliberately out of scope.)
+- **Clinical signals, opt-in and additive.** Validated self-checks for mental wellbeing and sleep (WHO-5, PHQ-9, GAD-7, Sleep Condition Indicator — official questionnaire wording, calm crisis-resource handling), grip strength, a 0–10 pain score, waist and body measurements, and a longevity lab panel — each added through one signal registry, so a new signal wires into charts, correlations, the coach, the FHIR map, and the API at once.
+- **Records, structured.** Allergies and family history as encrypted structured records that flow into the doctor report, plus lab values you key in or scan from a printed report — OCR extracts the stated values, units, and dates for you to review and confirm before anything is saved. HealthLog transcribes what a report says; it never interprets or diagnoses from it. (A general document vault is on the roadmap; immunization records are deliberately out of scope.)
 - **Context that explains the numbers.** An opt-in environmental module folds weather, daylight, and temperature in as influence signals (winter darkness against mood, heat against blood pressure) using a home location you set, so a pattern has somewhere to point.
-- **Your devices, one server.** Withings, WHOOP, Oura and Polar sync over OAuth2, Fitbit connects experimentally over the Fitbit Web API, an Apple Health `export.zip` folds your full history in, and the native iOS app streams HealthKit live. A per-metric source priority decides which reading is canonical when wearables overlap.
+- **Your devices, one server.** Withings, WHOOP, Oura and Polar sync over OAuth2, Google Health connects Fitbit and Pixel Watch through your own Google Cloud client, Nightscout streams CGM glucose, an Apple Health `export.zip` folds your full history in, and the native iOS app streams HealthKit live. A per-metric source priority decides which reading is canonical when wearables overlap.
 - **Medication tracking that tells the truth.** Flexible schedules (weekly injections, weekday-only, intervals, PRN, cyclic), a configurable intake window per dose, and a traceable dose history where every slot reads taken, late, skipped, or missed — the same ledger the compliance rate is computed from, so the percentage can never disagree with the timeline.
-- **AI insights you own.** Daily briefing, health scores, correlations, and a conversational coach grounded in your own measurements, with calm proactive check-ins it suppresses when there's nothing genuine to say. The coach describes your data, never diagnoses. Bring your own OpenAI or Anthropic key, or point at a local endpoint (Ollama, LM Studio, vLLM) so nothing leaves your network.
+- **AI insights you own.** Daily briefing, health scores, correlations, and a conversational coach grounded in your own measurements and interpreted against cited guideline reference bands — where a value sits and what that means in plain words, never a diagnosis.

 - **Clinician-ready output.** A doctor-report PDF generated client-side, a read-only HL7 FHIR R4 API, and scoped, time-limited share links you revoke after the visit.
 - **Private by construction.** AES-256-GCM encryption at rest with zero-downtime key rotation, passkey login, server-side sessions, strict CSP — and no third-party tracking anywhere.
-- **Built to be lived in.** Installable PWA with offline support, medication reminders over APNs, Telegram, ntfy, and Web Push, a sub-second dashboard on years of imported history, English and German end to end.
