/**
 * #1111 — Hide "My Channels" section entirely when empty.
 *
 * Acceptance:
 *   - localStorage cleared → no `.ch-section-mychannels` (no header, no
 *     placeholder text, no "My Channels" string in #chList)
 *   - PSK key stored in localStorage → `.ch-section-mychannels` exists
 *     with the header
 *
 * Usage: BASE_URL=http://localhost:13581 node test-channel-issue-1111-e2e.js
