   Design system: "liquid glass on light water"
   A pale canvas with large soft color fields drifting in a fixed layer
   behind the page. Every glass surface blurs that layer with
   backdrop-filter, so glass genuinely refracts moving color.

   Signature moments:
   · hero water surface — a live ripple simulation (canvas, script.js)
   · specular highlight that follows the cursor across glass panels
   · nav pill that morphs open into the menu
   · "clarity lens" on the community map (blurred art, sharp under lens)
   · flowline — scroll progress as a droplet running down a hairline

   Brand: navy #1f2150 · gold #b8932f · grey / white · black text
