Single-user routine checklist app for after-school tasks, with optional task timers and a parent PIN gate.

• main.tsx: HTTP entrypoint (export default app.fetch)
• backend/index.ts: Hono app + routes + HTML bootstrap
• backend/parentAuth.ts: server-side PIN verification + signed parent session cookie
• frontend/index.html: app shell
• frontend/index.tsx: React UI
• shared/tasks.ts: routine task list
• shared/types.ts: shared TypeScript contracts

Protected tasks require an environment variable with a SHA-256 hash of your parent PIN:

• Env key: ROUTINE_PARENT_PIN_SHA256
• Value format: lowercase 64-char hex SHA-256 digest

Generate a hash locally (macOS/Linux):

printf '1234' | shasum -a 256 | awk '{print $1}'

Set that output as the value for ROUTINE_PARENT_PIN_SHA256 in Val Town.

Optional hardening:

• Set ROUTINE_PARENT_SESSION_SECRET to a long random string.
• If not set, the app falls back to deriving session signing from the PIN hash.

Update routineTasks in shared/tasks.ts.

Example task entries:

Create val
{ name: "Do homework", timed: false }
{ name: "Brush teeth", timed: true, duration: 2 * 60 }
{ name: "Get parent check", timed: false, requiresParent: true }

• GET /api/parent/status: parent lock status
• POST /api/parent/verify: verify PIN and set HTTP-only session cookie
• POST /api/parent/lock: clear parent session cookie
