Summary

Redesigns the marketing site and docs with a LangChain-style information architecture, in dynavec's own warm ember-on-charcoal palette (kept the existing #E8623B brand coral; no LangChain branding or assets are used).

Brand

• New dynavec logo: SVG mark (a "v" of two vectors converging on a highlighted result node), light/dark wordmarks and favicon in opensource/dynavec/images/brand/.

Landing page (opensource/dynavec/)

• Floating nav with a Products mega menu (the four pillars, AWS, resources) and a mobile menu.
• Dark hero with the demo video in a product window, live GitHub stars and a works-with marquee.
• Interactive lifecycle orbit — Remember / Build / Observe / Measure — auto-advancing, with mock product panels for dynavec (search), dynaflow (supervisor graph), dynalogs (trace with redaction) and dynaevals (metrics + trend).
• Four pillars, one library cards (closes the content in Landing page: ecosystem section introducing the four pillars #309), how they fit together loop diagram (Landing page: "How they fit together" diagram #310) and an honest positioning table (Landing page: positioning vs LangChain / LangGraph (parity + differentiators) #311) with shipping / partial / roadmap markers.
• Keeps the existing architecture, benchmarks, cost calculator, code tabs, quick start and contributors sections and every script.js hook. New behaviour lives in site.js / site.css; shared tokens in styles.css re-tuned to the new palette.
• Copy only claims what ships today; roadmap items are labelled as roadmap.

Docs (tools/build_docs.py + docs/docs.css|js, HTML regenerated)

• New header: logo, centred ⌘K / Ctrl+K search across every page and section (search-index.js, generated), GitHub + Get started.
• On this page right rail with scroll-spy, and anchor links on section headings.
• Docs home: agent-lifecycle cards with status, Start-here cards, guides grid as cards.
• Fixes code blocks rendering without their dark background (a .doc pre.code specificity bug that is also live today).

Notes

• Landing page: ecosystem section introducing the four pillars #309 is assigned to @tikhandesanket — this PR covers the four-pillar section; happy to adapt to anything from that work.
• Verified in a browser at 1440px and 375px (no horizontal overflow), mega menu, mobile menu, lifecycle auto-advance/click/keyboard, search keyboard navigation, calculator and charts.
