Rest as a performance budget

How the seventh day maps to maintainability, caching, minimal JavaScript, and a calm production surface.

Completion is a technical feature

The seventh day is not an absence of work. It is the proof that the system is complete enough to stop adding machinery. Good templates should feel the same way: enough features to demonstrate the platform, but not so many abstractions that a real team must fight them.

Astro Genesis keeps JavaScript local to features that need it: menus, tabs, dark mode, and server-rendered interactions. The core pages remain mostly HTML and CSS.

Caching by default

Static routes are prerendered. Blog pages are generated from content collections. Dynamic routes exist where request context matters. Server islands let a static shell stay fast while personalized content arrives separately.

Deployment rest

The Docker build produces a standalone Node runtime. CI runs type checks and builds on every pull request. Dependabot groups Astro and Tailwind upgrades so framework changes arrive in reviewable batches.
