    Function buildPopupContent

    • Builds the popup content element for a set of resolved fields.

      <div class="gl-poi-popup">
        [<img class="gl-poi-popup__hero">]           ← hero, outside the body
        <div class="gl-poi-popup__body">
          <div class="gl-poi-popup__badges">…</div>   ← consecutive badges grouped
          [field nodes from the shared widget dispatch]
          <div class="gl-poi-popup__actions">…</div>  ← consecutive actions grouped
          <a class="gl-poi-popup__link">…</a>         ← last, only when hasSidepanel
        </div>
      </div>

      Three widgets get special treatment, all for LAYOUT reasons rather than rendering ones: a hero image closes the current body and attaches to the root, and consecutive badges — like consecutive actions — are buffered into a row of their own instead of stacking in the body's column. A row nothing rendered into is not attached: an action with no actionId renders nothing, and an empty container would still take its margin.

      Parameters

      • fields: readonly RenderField[]

        Render descriptors, in display order.

      • rawProperties: Record<string, unknown>

        The feature's properties as they came from the source.

      • ctx: RenderContext

        Render context — layer and feature identity, plus the click position.

      • opts: { hasSidepanel: boolean }

        hasSidepanel tells the builder whether a "see details" affordance has anywhere to lead; without one, it is not rendered at all.

      Returns HTMLElement

      The popup root element, ready to mount. Text is escaped at the sinks.
