0c7f37fd12 feat(quota): storage quota + family-member limits for free tier
Feature A — Storage quota (1 GiB per family):
- src/lib/quota.ts: enforcement library with pure functions (fully unit-tested)
  and DB-bound helpers; isPaidFamily() is the single payment abstraction gate
- src/lib/format-bytes.ts: extracted formatBytes() — safe for client imports
- POST /api/upload: quota check before presigned URL issuance (HTTP 402 + reason code)
- POST /api/memories/[id]/confirm: HeadObject reconciles actual R2 size; deletes
  over-quota objects and marks row failed rather than silently exceeding limit
- GET /api/storage-usage: storage info endpoint for UI meter
- src/components/StorageMeter.tsx: meter bar + StorageQuotaBanner + MemberLimitBanner
- memories/page.tsx: quota banner, FAB disabled (⊘) when exceeded, compact meter in header
- settings/page.tsx: always-visible StorageMeter + MemberLimitBanner in invite section

Feature B — Member limit (2 per family, free tier):
- invites/route.ts: replaced ad-hoc inline check with checkMemberLimit() from quota lib
  Structured 403 response: { reason, currentCount, limit }
- Freeze rule: paid→free downgrade leaves all members intact; only new invites blocked

Migration:
- drizzle/0007_subscription_status.sql: ADD COLUMN subscription_status varchar(20)
- debug-migration/route.ts: step added for hot-apply without full redeploy
- src/db/schema/family.ts: subscriptionStatus field added to Drizzle schema

Tests: 44 unit tests in src/__tests__/quota.test.ts, all passing
- Pure function tests (no DB): isPaidFamily, wouldExceedQuota, isAtMemberLimit, formatBytes
- DB-bound tests (mocked @/db): getFamilyStorageUsage, checkStorageQuota,
  checkMemberLimit, getStorageInfo, tenant isolation

c2cabc01d3 feat(g1-g4): design system, memories pipeline, medical tracking, AI brain
G1 — Design System: 14 UI primitives (Button, Card, Modal, Sheet, Input,
Textarea, Select, EmptyState, LoadingShimmer, ConfirmDialog, WashiTape,
Badge, Avatar, Tabs), PageTransition with Framer Motion, sun/moon CSS vars,
Caveat font, /dev/components visual showcase.

G2 — Memories Pipeline: R2 presigned uploads, Sharp thumbnail generation,
LiteLLM vision captions + pgvector embeddings, CSS masonry gallery with
infinite scroll, private toggle, semantic search fallback to ILIKE.

G3 — Medical: dose log + correction audit trail, IAP vaccine bulk import,
emergency escalation page, pediatrician phone in settings.

G4 — AI Brain: keyword guardrail → LLM classifier → structured DB tool-use
(7 tools) → memory search → general parenting handler; ai_usage table;
22-case medical bypass safety test suite.

DB migrations: 0011_memories, 0012_medical_doses, 0013_ai_usage.
