+  <p>Speckl is an <strong>open standard</strong> for specification-first development with dark provenance. It defines how to write what a system should do — in a machine-verifiable format — before any code is written. Every behavior traces back to its source of intent.</p>
+  
+  <p>Speckl is not a product or a platform. It is a <strong>methodology and language specification</strong>, published freely under MIT. The SpeckDL language, the Dark Provenance methodology, and the reference implementations define the standard. Products built on it — compilers, verification tools, compliance APIs — will come as the ecosystem grows.</p>

-      <h3>🎯 Specification-First</h3>
-      <p>Write what your system should do in SpeckDL, a constraint-based specification language. Z3 proves your specs are consistent before any code exists.</p>
+      <h3>📝 SpeckDL Language</h3>
+      <p>A constraint-based specification language that defines <em>what</em> a system does, not <em>how</em>. Specs are small, stable, and machine-verifiable — the audit surface for regulated systems.</p>
     </div>
     <div class="feature-card">
       <h3>🔗 Dark Provenance</h3>
-      <p>Every function, every branch, every side effect links back to its source — a regulation, a design decision, a conversation. Invisible until needed, always complete.</p>
+      <p>A methodology where every behavior traces back to its source — a regulation, a design decision, a conversation. The provenance graph is always present, materialized on demand for audits or debugging.</p>

-      <h3>🤖 Multi-Agent System</h3>
-      <p>Orchestrator, team leads, and SMEs collaborate on specs. The harness scales automatically under load. No human coordination required.</p>
+      <h3>🧩 Reference Implementations</h3>
+      <p>Minimal reference tools for SpeckDL parsing, Z3 constraint verification, and provenance graph generation. The building blocks for tooling, not a production system.</p>

-      <h3>🛡️ Regulated by Design</h3>
-      <p>Speckl targets DO-178C, IEC 62304, ISO 26262, FDA 21 CFR 820. Compliance is structural, not bolted-on.</p>
+      <h3>🏗️ Ecosystem-First</h3>
+      <p>The standard is the foundation. Consulting, SaaS tooling, and compliance APIs will build on it — validated through real-world use before they ship.</p>
