/**
 * PopupLayer (spec: "PopupLayer (built-in `<om-layer type="PopupLayer">`)").
 * Dense, WebGL-rendered geo-annotations — a deck.gl CompositeLayer, not a
 * DOM system. deck.gl's own TextLayer already renders a background rect
 * behind its glyphs (`background`/`getBackgroundColor`/`backgroundBorderRadius`/
 * `backgroundPadding`), which covers "quad geometry for backgrounds" without
 * hand-rolling a separate polygon layer — one TextLayer per layout, not a
 * multi-layer composition.
 *
 * `layout="card"`'s subtext is folded into `getText` as a second line (`\n`)
 * rather than a second stacked TextLayer, so both lines share ONE background
 * box instead of two overlapping ones — a deliberate simplification.
 *
 * `getIcon` is accepted in the schema (forward-compatible with the spec's
 * accessor list) but not yet wired to an IconLayer sub-layer — that needs an
 * icon atlas/mapping the spec's own example doesn't exercise, so it's an
 * honest, documented gap rather than a half-built icon system.
