+//
+// Capabilities:
+//   - Private feeds: optional custom HTTP headers (e.g. "Authorization: Bearer …")
+//     are attached to every request, both to the feed and to article pages.
+//   - Full text: when an item exposes a link, the article page is fetched and
+//     run through a readability extractor; the cleaned HTML is converted to
+//     Markdown. Feed-provided content (content:encoded / description) is used
+//     as a fallback.
+//   - Incremental: a per-feed fingerprint (item updated/published time, or a
+//     content hash when no timestamp is present) detects changed items so only
+//     new/updated articles are re-fetched. Deletions are NOT synced — feeds
+//     routinely drop old items, which would otherwise look like deletions.
