/**
 * Composes source-list sections from `usePaymentSources` buckets +

 * discriminated layout shape; the composer (`SourceList`) dispatches
 * to the matching layout primitive.
 *
 * **Default branch** (most customers) mirrors SourceList's prior
 * output:
 * - `isSwappedEnabled=false` → flat layout. One group for `preferred`
 *   (if any), one combined group for `moreSources + unavailable` (if
 *   any), with a single divider between them. (`SourceList` places
 *   `<PayPal />` as the flat footer.)
 * - `isSwappedEnabled=true` → grouped layout. Same two groups, but
 *   rendered in separate boxes with `showLabels` toggling the section
 *   headers ("Connected" / "Most popular" / "More options"). The
 *   "More options" header is suppressed when no preferred group
 *   precedes it.
 *
 * **Aave branch** (per Figma, [ENG-3743](https://linear.app/funxyz/issue/ENG-3743)
 * + [ENG-3747](https://linear.app/funxyz/issue/ENG-3747)
 * + [ENG-3755](https://linear.app/funxyz/issue/ENG-3755)):
 * - "Native" section with the user's underlying-asset row when
 *   `nativeRow` is provided.
 * - Second section flattens preferred + moreSources + unavailable
 *   into "Use other assets" (with native present) or "Use any asset"
 *   (without). Header carries a tooltip via `labelTooltip`.
 * - Layout is always `grouped` with `showLabels=true` for Aave so the
 *   section headers render.
