      <span class="mapsub">— what's real, what's predicted, and where it gets sharper. Honest by design; a read runs 100% on-prem.</span></div>
    <div id="howWrap">
      <div class="how-grid">
        <div class="how-card"><h4>1 · Structure → numbers</h4><p>Every molecule becomes a <b>2,048-bit Morgan fingerprint</b> (which substructures it contains) plus a block of <b>physicochemical descriptors</b> (logP, MW, TPSA, H-bonding…). That one shared vector feeds every model — the same structure-to-property representation QSAR has leaned on for decades.</p></div>
        <div class="how-card"><h4>2 · Taste — 6 trained heads + 2 rules</h4><p>Six <b>random-forest</b> classifiers (sweet, bitter, umami…) each return a probability, scored by an honest held-out <b>CV-AUROC</b>. Sour and salty are solution / ionic effects, not molecule-shape ones, so they're transparent <b>rules</b> — not faked models. A sweetness-intensity regressor estimates relative-to-sucrose potency.</p></div>
        <div class="how-card"><h4>3 · Aroma — 164 odor heads</h4><p>One random forest per descriptor (citrus, floral, woody…), trained on <b>public-domain odor text</b>. A head ships only if it clears <b>CV-AUROC ≥ 0.70</b> — 164 survive, each shown with its own score. It reads <b>presence, not intensity</b> (free text carries none) — an honest ceiling, stated in the UI.</p></div>
        <div class="how-card"><h4>4 · Honest by design</h4><p>Every value is tagged <b>measured / predicted / estimate</b>, so nothing reads as more precise than it is. Where a quantitative feature needs data we can't ship free-commercially (odor thresholds, panel intensities), the UI <b>says so</b> — and it lights up with <b>your</b> data.</p></div>
        <div class="how-card"><h4>5 · Formulation, not just molecules</h4><p>The <b>Formulation Studio</b> reads a whole recipe before you pour — weighting each ingredient by odor impact, aggregating the blend's note-profile, flagging the overpowering component, and closing the gap to your target. That's single-molecule ML turned into a bench tool.</p></div>
        <div class="how-card"><h4>6 · On-prem &amp; commercial-clean</h4><p>Nothing leaves the box — a read makes <b>no cloud calls</b>. The shipped models train only on <b>public-domain or permissively-licensed</b> data, so the commercial edition stays clean (provenance tracked in the repo).</p></div>

        <div class="map-method-body">
          <p><b>Method.</b> Each molecule becomes a 2048-bit <b>Morgan fingerprint</b> (radius 2 —
          a bit for every local atom environment). Distance between two molecules is
          <b>Jaccard = Tanimoto</b> on those bits, the standard chemical-similarity measure. That
          high-dimensional space is projected to 2D/3D with <b>UMAP</b>, which preserves each
          molecule's <i>local neighborhood</i> — so dots that sit together really are built from
          the same substructures. The layout is deterministic (fixed seed).</p>
          <p><b>How to read it.</b> The <i>positions</i> come purely from <b>structure</b>; the
          <i>colors</i> are a flavor label laid on top. Where a color forms a clean island,
          structure alone predicts that flavor (e.g. sugar-like polyols cluster sweet; alkaloid
          scaffolds cluster bitter). The interesting molecules are the <b>off-color dots inside
          another cluster</b> — a bitter point sitting among sweeteners is a structure that breaks
          the trend, exactly the kind of lead worth a closer look.</p>
          <p><b>Two flavor dimensions.</b> Flip the color toggle between <b>taste</b> (sweet /
          bitter / umami / sour / salty / tasteless) and <b>aroma</b> (= odor — the same thing;
          the 164 documented descriptor classes like citrus, floral, sulfurous). Same molecules,
          same structural layout — you're overlaying a different sense. The <b>both</b> toggle merges
          them into one full-flavor view: each dot takes its <b>taste</b> color where a taste is known,
          otherwise its <b>aroma</b> color — so nearly every molecule is colored by its dominant known
          flavor property. Comparing taste-only vs aroma-only vs both shows where the two senses align
          (a sweet-tasting molecule that also reads floral) versus diverge.</p>
          <p><b>Honest caveats — and the fix.</b> The <i>similarity</i> (UMAP) layout has axes with
          <b>no units</b>; only local distances mean anything. When you want <b>real, labelled
          axes</b>, switch the layout toggle to <b>property axes</b>: the same dots replotted on
          <b>molecular weight</b> (x, in daltons) vs <b>logP</b> (y — hydrophobicity, oil-vs-water
          partitioning), with gridlines and a logP = 0 waterline. That view <i>is</i> a metric
          space — you can read a molecule's size and greasiness straight off the axes, and watch a
          taste/aroma color track (or not track) those physical properties. In <b>3D</b>, property
          axes add a real third dimension: <b>TPSA</b> (topological polar surface area — polarity /
          H-bonding), so it's MW × logP × TPSA. Two lenses on the same molecules:
          <b>similarity</b> for neighbors &amp; outliers, <b>property axes</b> for physical structure.</p>
