Avoid Creating Objects Just to Call `getClass()`

Ensure that objects are not created solely for calling getClass(). Use ClassName.class instead.

Why this matters

Creating an object solely to call getClass() wastes memory and CPU cycles. Use ClassName.class instead.

Side-by-side examples engineers can pattern-match during review.

Avoid

MyObject myOb = new MyObject();  // Noncompliant
Class c = myOb.getClass();

Prefer

Class c = MyObject.class;

From the same buckets as this rule.

Avoid Blocking Calls to Async Methods
Blocking async methods with `.Result` or `.Wait()` can cause deadlocks and prevent efficient asynchronous execution. Use `await` instead for proper async behavior.

Fingerprint assets and cache immutably
All static JS/CSS/font/image files MUST use content-hashed filenames (e.g., app.9c1a7b.js) and be served with "Cache-Control: public, max-age=31536000, immutable". HTML and other non-fingerprinted documents MUST be served with "Cache-Control: no-cache" (or equivalent) to enable conditional revalidation.

No live network or DB in unit tests—use fakes/mocks
Unit tests must stub or fake external HTTP/DB calls; allow real I/O only in integration/e2e tests tagged accordingly.
