DS4AI, the Design Suite for AI, is Polymathie-Studio's suite of small, dependency-free instruments for building websites, dashboards, and tools, increasingly by an AI. Each closes one axis of the invisible-correctness layer, the part of a shipped surface a look-at-it review cannot see and that fast, AI-assisted building drops: the state no one triggered, the keyboard no one used, the metadata no crawler read, the error no one hit, the key left in the bundle. Each is a drop-in you compose instead of reinventing.

- TEMPER: legibility. A semantic design-token system with a palette solved to verified contrast floors, so color never drifts across components and the page reads for a reader who is not the designer.
- LUCID: honest disclosure. Complexity placed so a reader is never walled with all of it nor floored into false simplicity, with every claim reachable to its basis.
- GRACE: off-happy-path states. The reusable loading, empty, error, and not-found states that render LUCID's principle, so a surface never ships the happy path alone.
- HASP: privacy. An AI tool runs on the user's own key, held in the browser and never sent to a server.
- GRASP: operability. Accessible-by-default interaction components, the WAI-ARIA common working set, keyboard-operable and screen-reader ready, the controls AI builds get wrong.
- BEACON: findability. A build and SSR-time generator for the head metadata, social cards, structured data, and site files a page needs to represent itself to search engines, shares, and agents.
- FLEET: delivery. Responsive-image and picture markup, resource-hint and font tags, and cache config against the Core Web Vitals, so a page loads fast and does not shift.
- MISSING: the standard for the invisible-correctness layer. It names the axes, routes each to its instrument, and ships the machine-readable family manifest and a conformance auditor that checks a shipped surface against all of them.
Each instrument has a zero-dependency core, ships so no build step is required of the consumer, is accessible by default, and composes with the others. DS4AI joins PT4AI and PC4AI in Polymathie-Studio's family of corpora served to an AI.
