Platform architecture
Blueprint for scalable AI
How dex28 stays coherent from the gateway to your storage tier — with the same visual language we call The Architect.
Runtime flow
Traffic moves predictably through the stack:
- Gateway — auth, rate limits, request shaping
- Custom logic — your routers, tools, rubrics, retrieval
- Proxied LLMs & perception — unified quotas and telemetry
- Storage & queues — durable artifacts, replay, and burst absorption
Benefit: engineered for any scale — RBAC enforces governance across every solution surface, from internal APIs to customer-facing agents.
Design system · overview
Surfaces use square geometry (no border radius) for a rigid control-plane read: strong type scales, asymmetry, and a high-contrast foundation.
Technical tone is conveyed with fine lines, 48px grid rhythm, and restrained motion.
Colors
Material-style tokens (examples):
- background / surface · #131313
- primary · #ffffff · on-primary · #1a1c1c
- secondary · #c6c6c6
- error · #ffb4ab · outline-variant · #474747
No-line rule: prefer tonal surfaces. Ghost borders: outline-variant at low opacity when containment is required.
Typography
- Space Grotesk — display, labels.
- Inter — body copy at comfortable line height (~1.6).
Elevation & depth
Stack surface tiers: lowest for recessed panels, highest for lifted chips. Glass on nav via backdrop blur.
Components
- Primary button: solid primary, ~0.25rem radius; hover to primary-container in ~150ms.
- Secondary: ghost control on outline-variant at low opacity.
- Technical grid: 48px intervals.
Do
- Generous whitespace; 12-column grid.
- Subtle motion when purposeful.
Don’t
- Large radii or playful pills for core chrome.
- Non-monochrome accents except errors.
