Today's developments reveal how teams are pushing the boundaries of both AI-assisted development and traditional web engineering. From "dark factories" where humans never review AI-generated code to clever localStorage tricks that add dynamic features to cached sites.

• AI coding maturity model: Dan Shapiro's five-level framework spans from "spicy autocomplete" (GitHub Copilot) to "dark factory" teams of <5 people who never review AI code—they focus entirely on testing systems and proving the software works, with 20+ year veterans achieving months of robust development.

• Dynamic features on cached sites: Simon Willison shows how localStorage enables admin-only edit links and persistent random navigation on aggressively cached (15-minute Cloudflare) sites—the random tag feature uses 5-second timestamps to maintain state across page loads without breaking cache efficiency.

• Typography for technical writing: Martin Fowler warns that excessive bold formatting (increasingly spread by LLMs) loses all emphasis power—he recommends italics for in-text emphasis, bold only for unfamiliar terms at their explanation point, and callouts instead of bolded sentences for skimmable highlights.

• CSS corner evolution: The new corner-shape property lets you create beveled, scooped, notched, and squircle corners with simple CSS instead of the complex pseudo-element hacks required just 10 years ago, though browser support remains limited to Chrome-based browsers.
