What Is the Sovren Stack?

The Sovren Stack is three products that keep work, identity, and assets under owner control:

Product	Layer	Status

Architecture

Theme System (Light / Dark)

The site supports light and dark modes with a cinematic toggle in the navigation.

• Default: Light mode (:root / [data-theme='light'])
• Toggle: Button in Nav.svelte calls toggleTheme() in +layout.svelte
• Persistence: localStorage.getItem('theme') with system preference fallback via prefers-color-scheme
• Mechanism: data-theme attribute on <html> drives CSS variable swaps
• 3D sync: SceneManager.js observes data-theme via MutationObserver and updates fog, wireframe, grid, and particle colors in real time

All colors use CSS custom properties — no hardcoded color values in components.

3D Scene (Three.js)

A full-viewport 3D background renders behind all page content:

• Canvas: position: fixed, z-index: -1, pointer-events: none — sits behind all UI
• Elements: Rotating wireframe cube, inner octahedron, infinite grid, volumetric dust particles
• Interaction: Mouse parallax on cube rotation, scroll-linked grid drift
• Theme-aware: Materials, fog color/density, and particle opacity adapt to light/dark mode
• Lifecycle: Scene.svelte mounts/unmounts the canvas; SceneManager.js handles the animation loop and cleanup
• Accessibility: Animations fully disabled when prefers-reduced-motion: reduce is set — checked at runtime and via CSS media query
• Memory: destroy() correctly removes all event listeners using stored bound references, disposes all Three.js geometries and materials

ProductMonoliths.svelte exists as an interactive wireframe panel component but is currently unused — it was removed from the home page to reduce visual clutter.

Shared Components

Product pages (Esver, Visage, MrHaven) share four components with zero local CSS:

Component	Props	Purpose
ProductHero.svelte	title, category, status, tagline, size	Hero section
Overview.svelte	lead, specs[], stackNote, slot	Overview with spec table
PillarList.svelte	label, pillars[]	Numbered feature list
CtaSection.svelte	title, body, actions[]	Call-to-action with buttons

Design System

Centralized in src/app.css with 60+ design tokens covering:

• Colors — Theme-aware via --bg, --surface, --border, --text-primary/secondary/muted/ghost
• Typography — Fluid clamp() scale from --fs-hero down to --fs-label-xs
• Spacing — --space-xs through --space-7xl
• Layout — --max-w, --max-w-prose, --nav-h, --z-nav
• Transitions — --transition-fast, --transition-slow

Rules: one typeface only, no color for emphasis (use weight/spacing), all values via tokens.

Deployment

npm run check        # must pass before pushing
npm run lint         # must pass before pushing
npm run build        # verify build passes
git push             # GitHub Actions auto-deploys from main

• Output: dist/ directory (static adapter)
• DNS: 4 GitHub Pages A records + www CNAME → sovren-software.github.io, proxied via Cloudflare
• static/CNAME contains sovren.software — do not delete
• CI runs check → lint → build in sequence before deploying

Security Headers

GitHub Pages cannot set HTTP response headers. Security is enforced at two levels:

1. Browser-level (active now): Content-Security-Policy, Referrer-Policy, and X-Content-Type-Options are set via <meta http-equiv> in app.html
2. CDN-level (manual): X-Frame-Options, HSTS, COOP, CORP, and Permissions-Policy must be configured as Cloudflare Transform Rules — see SECURITY.md for exact steps

The static/_headers file is the authoritative record of all required headers and will be auto-enforced if the site ever migrates to Cloudflare Pages.

SEO & AI Discoverability

• app.html — JSON-LD structured data (Organization + WebSite schemas), favicon suite, manifest, OG/Twitter defaults
• Each page — <svelte:head> with unique title, description, Open Graph meta, Twitter Card tags, and canonical URL
• static/og-image.png — 1200×630 social preview image rendered with actual Geist Mono font via Satori
• static/llms.txt — full product descriptions for AI crawlers (ChatGPT, Perplexity, Claude)
• static/sitemap.xml — all 5 routes with <lastmod> dates
• Cloudflare proxy prevents GitHub/Fastly from blocking AI crawler IPs
• Bing Webmaster Tools verified

Code Quality

• Linting: ESLint with eslint-plugin-svelte — run via npm run lint
• Type checking: svelte-check — run via npm run check
• Formatting: Prettier with prettier-plugin-svelte — run via npm run format
• CI: GitHub Actions runs check → lint → build on every push to main
• Dependencies: Dependabot configured for weekly npm dependency PRs

Email Signup + Funnel (Brevo)

The site now routes the Esver CTA through a configurable marketing URL in src/lib/marketing.js.

1) Wire the signup link

Edit src/lib/marketing.js and set:

export const BREVO_SIGNUP_URL = '__SET_BREVO_SIGNUP_URL__';

to your Brevo hosted signup form URL (example format: https://xxxx.sibforms.com/serve/...).

If not set, the CTA falls back to mailto: so the button still functions.

2) Brevo dashboard setup (minimal)

1. Create list: MAIN_NEWSLETTER
2. Create a sign-up form (Marketing → Forms)
3. Enable double opt-in
4. Set destination list to MAIN_NEWSLETTER
5. Copy hosted form URL into src/lib/marketing.js
6. Create automation: trigger on contact added to MAIN_NEWSLETTER
7. Add one email step (delay 1–2 minutes), then activate

2.5) Phase 2 cohesive UX behavior

• The Esver page now includes a native launch briefing section with an embedded Brevo form iframe.
• If the signup URL is not an embeddable http(s) URL, the page automatically falls back to a direct CTA link.
• The closing CTA now routes users deeper into the ecosystem (/ecosystem + /visage) to avoid duplicate signup prompts.

3) Single welcome email template (v1)

Use this as the first and only automation email for now:

Subject: Welcome to Sovren — launch briefing subscribed
Preview: You are in. We will send one launch briefing and occasional high-signal updates.

Body:

You are subscribed to the Sovren launch briefing.

What you should expect:
- One operational briefing when Esver OS goes live
- Occasional high-signal updates across the Sovren Stack (OS, identity, programmable finance)
- No spam. No feed noise. No growth-hack sequences.

Why this exists:
Sovren builds software for operators who want leverage without surrendering control.
Privacy is not a feature. Sovereignty is the baseline.

Explore the stack:
- Esver OS: https://sovren.software/esver
- Visage: https://sovren.software/visage
- MrHaven: https://sovren.software/mrhaven

https://sovren.software

4) Verification checklist

1. Open /esver and verify the launch briefing section renders.
2. Confirm iframe form loads (or fallback button appears if embed unavailable).
3. Submit a test email and confirm contact lands in MAIN_NEWSLETTER.
4. Confirm the single welcome automation email is sent.
5. Confirm /ecosystem and /visage links in final CTA work.
