1.3 System Invariants & Structural Requirements
“Design is a system, not a style.” — Massimo Vignelli
The Standard ecosystem enforces a rational, mathematical order on document typesetting. By stripping away visual compromises and arbitrary parameters, the system guarantees optimal layout balance and legibility.
1. Core System Properties
The architecture of the @stnd framework is governed by four non-negotiable invariants:
- Aesthetic Autonomy: Typesetting balance is achieved mathematically via the golden ratio ((\varphi = 1.618)) and a rigid vertical grid. Visual harmony is enforced programmatically at render time; no manual override is allowed.
- Throughput Latency: The pipeline from plain text input submission to edge-published URL must execute within a 10-second threshold.
- Data Independence (File-Over-App): Source files must remain in plain, uncompiled Markdown. Applications and client interfaces are transient; the file is the permanent source of truth.
- Resource Constraints: System footprint must be minimized. Codebases must execute at the Edge with zero cold starts, utilizing minimal bandwidth and memory.
2. Definitive Target Interfaces
Every package, module, and configuration is designed to satisfy three target performance requirements:
- The Author Interface: Maintain a distraction-free writing environment. The framework automatically parses simple Markdown inputs and formats them into grid-aligned typography, requiring zero manual configuration.
- The Reader Interface: Deliver pages with zero layout shifts, zero tracking scripts, and sub-second load times.
- The Resource Footprint: Target infinite horizontal scaling on Cloudflare’s Edge network with negligible compute costs.
3. Engineering Discipline
To prevent code rot and maintain system integrity, three engineering rules are enforced:
- Zero Shims: Deprecated APIs are purged immediately. No backward compatibility layers or shims are tolerated in the core codebase.
- Separation of Concerns: Astro files (
.astro) are strictly declarative layouts. Business logic, data parsing, and model orchestration must reside exclusively in TypeScript classes and helpers. - Vertical Slice Architecture: All features are encapsulated inside
modules/. Slices are isolated; removing a slice directory must disable the feature cleanly without leaving artifacts or breaking system builds.
