        <h2 class="text-lg font-semibold text-white mb-3">What is this?</h2>
        <p class="text-sm text-slate-400 leading-relaxed mb-4">
            A research tool for tracking, categorizing, rating, and mapping standardization
            documents on AI and agent-related topics across six standards bodies:
            <span class="text-slate-200">IETF</span>,
            <span class="text-slate-200">ISO/IEC</span>,
            <span class="text-slate-200">ITU-T</span>,
            <span class="text-slate-200">ETSI</span>,
            <span class="text-slate-200">NIST</span>, and
            <span class="text-slate-200">W3C</span>.
            It uses Claude for analysis and rating, Ollama for embeddings, and SQLite for storage.
        </p>
        <p class="text-sm text-slate-400 leading-relaxed">
            The dashboard provides interactive visualizations of the standardization landscape,
            including category breakdowns, rating distributions, author networks,
            extracted ideas, and gap analysis — answering the question:
            <em class="text-slate-300">Where is the AI agent standards race heading, and what's missing?</em>

        <p class="text-sm text-slate-400 leading-relaxed mb-4">
            IETF drafts are discovered via the
            <a href="https://datatracker.ietf.org" class="text-blue-400 hover:text-blue-300 transition">IETF Datatracker API</a>
            by searching abstracts for the keywords below
            (only drafts since <span class="text-slate-200 font-medium">{{ fetch_since }}</span>).
            ISO, ITU-T, ETSI, NIST, and W3C documents are sourced from their respective public catalogs
            using related search terms.

            <p><span class="text-slate-200 font-medium">2. Rate</span> — Claude rates each draft on 5 dimensions (novelty, maturity, overlap, momentum, relevance) from 1–5, with per-dimension explanations.</p>
            <p><span class="text-slate-200 font-medium">3. Categorize</span> — Claude assigns one or more topic categories (e.g., "A2A protocols", "Agent identity/auth").</p>
            <p><span class="text-slate-200 font-medium">4. Extract Ideas</span> — Claude extracts distinct technical ideas from each draft, with novelty scores.</p>

                Keywords determine which drafts are included. Broad terms like "agent" and "autonomous" cast a wide net
                (catching some tangentially related drafts), while specific terms like "ai-agent" and "agentic" target
                the core AI agent space. The false-positive flag in ratings helps filter out irrelevant matches.
                Suggestions for additional keywords are welcome.
