+/**
+ * DaoTekno (daotekno.com) LNReader plugin
+ *
+ * daotekno.com serves the DaoTranslate.com catalog — pages are titled
+ * "DaoTranslate.com - Web Novel Reader" and chapter footers link to
+ * DaoTranslate (the connection mentioned in the plugin request). It is a
+ * custom PHP reader, not WordPress/Madara:
+ *
+ * - Catalog:      `/?page=N` — 50 `a.novel-card.novel-item` rows per page,
+ *                 title in `.novel-title`, page marker `N / M`.
+ * - Search:       `/?q=<term>` — filtered server-side, same card markup,
+ *                 single page (page parameters are ignored).
+ * - Novel page:   `/series/<slug>/` — `<h1>` title, chapter tiles in
+ *                 `#allChaptersGrid` (`.chapter-box`, newest first) split
+ *                 across `?page=N`, 200 per page.
+ * - Chapter page: `/series/<slug>/<chapter>/` — text inside `#novel-content`.
+ *
+ * The site gates chapter pages on User-Agent: desktop UAs receive a
+ * "Mobile Only Content" interstitial instead of the chapter, so every
+ * request sends a mobile browser UA.
