quell. Quiet the cascade, not your design.

A production-ready CSS architecture system. Built from first principles. Owned permanently.

Live theme switch | token overrides in action | Five named cascade layers | Zero-specificity architecture | No build step

quell Architecture System

Architecture before components.
Mathematics before convention.
Foundation for the digital craft.

Four production-ready files. No build step. No framework lock-in. Adopt one layer—or the entire architecture.

quell-base.css

The Baseline

Production-ready CSS baseline for modern browsers. Establishes resolved design tokens, browser consistency, a minimal baseline, and form normalization across five named cascade layers. FOUC firewall.

quell-core.css

The Override Surface

An unlayered architecture theming that overrides every quell layer naturally. Replace tokens —not selectors.

quell-light.css

The Architecture

Production-ready components, utilities, responsive layout, and token-driven design built on the quell foundation.

quell-light.js

The Behavior Layer

Zero-dependency ES module. Toggle states, modal focus trapping, scroll-spy, — nothing more.

Architecture over abstraction. Variables over configuration. Ownership over subscription.

No tracker. No noise. Just the work.

Technical Documentation

Every architectural
decision documented.
