utils/logger.cts — console-compatible log.{debug,info,warn,error} with:
- level gating (LOG_LEVEL; debug in dev / info in prod), and
- REDACTION of secrets/PII (sensitive keys + bearer/JWT) so tokens,
passwords, and encrypted values never reach the logs (financial app).
Backend is abstracted (console now, swappable to pino later).
Swept all 317 server-runtime console.* across 35 files → log.* + inserted
the import at correct scope. tests/logger.test.js pins the redaction
contract (4 tests). CODE_STANDARDS updated; raw console.* is now banned in
server code.
Verified: check:server + typecheck:server + lint clean; 240/240 server
tests; client 50/50; build; e2e probe 17/17; boot smoke logs flow through
the logger and graceful shutdown intact.

Two of the large foundational services. billsService (validation/normalization,
balance math) is required by many others; notificationService (email + push +
drift digest) uses the shared http types indirectly.
Behavior-preserving. Verified: typecheck:server 0, check:server 0, suite 226/226.
