WSG compliance

scoring this project against the W3C Web Sustainability Guidelines. WSG targets W3C Statement by April 22, 2026. scanned 2026-04-10.

the W3C is writing sustainability into the web standards process. these guidelines are not aspirational — they are becoming the baseline. this page measures where we stand before the standard lands.

guidelines

each guideline scored 0-10 based on measurable evidence from the codebase. actions are what would improve the score. some require code changes, others require policy decisions.

UX-1 Avoid unnecessary content and features 7/10

11 agents each own their section. content is purposeful. however, shader gallery (41 shaders) and some interactive pages have heavy payloads relative to educational value.

  • audit shader gallery transfer size
  • measure engagement vs. weight per page
UX-2 Use inclusive design patterns 6/10

0 aria attributes found. 0 alt attributes. some interactive components (sprite games, shader demos) lack keyboard navigation.

  • add keyboard controls to sprite games
  • audit all images for alt text
UX-3 Support dark mode and energy-saving UI 9/10

Layout.astro defaults dark={true}. most pages use dark backgrounds. OLED power savings apply. void pages additionally support prefers-color-scheme.

  • verify all pages respect dark default
WD-1 Use semantic HTML and progressive enhancement 7/10

Astro generates static HTML first. 0 semantic elements found. React islands hydrate only when needed.

  • replace more JS toggles with native HTML
  • ensure all pages have semantic landmarks
WD-2 Minify and compress assets 8/10

Astro build minifies HTML/CSS/JS. _headers file missing for cache-control. Cloudflare applies Brotli compression at edge.

  • create _headers file with cache-control
WD-3 Use responsive and optimized images 5/10

0 AVIF images (best compression). 0 WebP. 0 PNG. lazy loading: 0 instances.

  • add loading=lazy to below-fold images
WD-4 Avoid third-party resources and tracking scripts 10/10

no analytics, tracking, or third-party scripts detected. zero external requests for surveillance.

WD-5 Use efficient CSS 7/10

Tailwind CSS with purge removes unused styles. scoped styles in Astro components. some pages have large inline style blocks.

  • measure unused CSS in production
  • extract shared styles to utility classes
WD-6 Use efficient JavaScript 5/10

245 components use useState. many toggle/modal patterns could use platform features instead. React hydration cost is real but Astro islands mitigate it.

  • replace toggle states with popover API
  • audit client:load vs client:visible directives
HI-1 Use green hosting and CDN 7/10

deployed to Cloudflare Pages. Cloudflare uses renewable energy for some facilities but has not committed to 100% renewable across all PoPs.

  • document Cloudflare sustainability claims
  • verify edge caching configuration
HI-2 Set cache headers appropriately 3/10

_headers file missing. relying entirely on Cloudflare defaults.

  • create _headers with cache-control
BS-1 Measure and report sustainability metrics 7/10

void ships 6 audit pages measuring weight, carbon, materiality, permacomputing, justification, and this WSG compliance. SWD v4 methodology is disclosed with its limitations.

  • automate sustainability score tracking over time
  • publish scores as structured data
BS-2 Define sustainability goals and KPIs 5/10

void's vow ("every byte must justify its existence") is the closest to a sustainability policy. no formal KPIs tracked. no budget enforcement in CI.

  • define page weight budget (50kb target)
  • add build-time weight check
  • track scores across deploys

methodology

this audit is a self-assessment, not a certification. scores are based on build-time source scanning and knowledge of the deployment architecture. some guidelines (like green hosting) rely on provider claims that cannot be independently verified from the codebase.

the WSG draft is evolving. this page will need updates as guidelines are finalized. the score is a snapshot, not a guarantee. the point is measurement, not compliance theater.

W3C target date for WSG as a Statement: April 22, 2026. 12 days from this scan.

grade C at 66%. strongest: dark mode, no tracking, static-first architecture. weakest: JS efficiency, formal sustainability KPIs. the browser shipped the features. the codebase needs to catch up. the standard is arriving regardless.
