The "Public offer" link in the Wallet pointed at the same-origin static
/offer/ page with a plain target=_blank anchor and no click handler. The
Android VK client ignores target=_blank and navigates its own WebView to
the page, stranding the player with no way back to the game (iOS opens a
child browser, so it was unaffected). The existing onExternalLinkClick
router could not help: it escapes only cross-origin links, and /offer/ is
same-origin (a static legal page, not an SPA route).
Add onInAppPageLinkClick, which routes a same-origin, non-SPA page out
through the host escape hatch (Telegram openLink, VK away.php) while
bypassing the cross-origin gate, and attach it to the offer link. Outside
a Mini App host it is a no-op and the anchor's own target=_blank stands.
The "Rules" (About) and ad-banner links already route correctly
(cross-origin + a handler) and are left unchanged.
