System Load Time & HTML 5.2 Standards

This document outlines the performance benchmarks, baseline network expectations, and structural compliance tests for documents hosted on bbsys.net. We enforce strict payload caps to guarantee sub-second rendering across all network interfaces.

Performance Baseline & Targets:

Initial Packet Budget: Total document size (HTML + inline assets) must remain under 14.6 KB to fit within the initial TCP slow-start congestion window.
Time to First Paint (TTFP): Target render time is under 50ms on broadband and under 200ms on legacy 3G or constrained mobile connections.
Zero External Requests: Pages must render fully without blocking on third-party fonts, external stylesheets, or analytics scripts.
Layout Stability: Explicit width and height attributes must be declared on all image tags to prevent cumulative layout shift during browser parsing.

HTML 5.2 Conformance Matrix:

Document Type Declaration: Strict adherence to <!DOCTYPE html> (HTML 5.2 standard).
Character Encoding: UTF-8 declared via <meta charset="utf-8"> in the document head.
Semantic Markup: Use of HTML 5.2 structural elements (<header>, <nav>, <main>, <article>, <footer>) for proper document outline.
No Dynamic Scripting: Zero client-side JavaScript execution required for primary navigation, visual layout, or document reading.
