## Selected guides

- [Omarchy on a Mac With UTM: What Works on Apple Silicon and What Does Not](https://www.nyk.dev/blog/omarchy-on-mac-utm): The official ISO is x86_64, emulation is unusably slow, and the ARM path needs software rendering. A decision matrix, the documented UTM build, and the fix list.
- [content-visibility: auto Shifts Your Page Until You Measure the Estimates](https://www.nyk.dev/blog/content-visibility-measure-intrinsic-size): A hover test that failed one run in four led to a chunk estimated at 800px and rendered at 1756px. The script that measures every estimate, and the table it printed.
- [A Flaky Playwright Hover Test Was a Real Layout Shift (Flake Triage Ladder)](https://www.nyk.dev/blog/flaky-playwright-hover-test-root-cause): Five rungs from 'whose server is on :3000' to Playwright's own actionability log, and the two page fixes that took a one-in-four failure to 16 of 16 with retries off.
- [Design With AI Without Shipping AI Slop](https://www.nyk.dev/blog/design-with-ai): Constrain the system before you describe the screen: tokens as hard limits, a three-pass review order, and the one deviation you choose yourself.
- [Research With AI Without Fake Citations](https://www.nyk.dev/blog/research-with-ai): Tier sources before you read them, keep every claim bound to its origin, and catch the laundering that makes a roundup look like corroboration.
- [Code With AI: Specify, Generate, Verify, Integrate](https://www.nyk.dev/blog/code-with-ai): Generation got cheap and review did not. Diagnose which of the four jobs is your real constraint, then fix that one before the others.
