Threads on this forum reach four-digit page counts, and stepping one page at a
time was the only movement the navigation bar offered. The end of a thread, or
any specific page, was effectively unreachable on a phone.

Jump targets are derived arithmetically from the forum's own page size instead
of read from the rendered pagination, because phpBB never renders more than a
handful of page links regardless of thread length. Where that page size cannot
be determined, the bar falls back to the links the forum itself provides and
hides the jump.

Both userscripts inject their stylesheet on thread pages, so class names are a
shared namespace between them. The new ones avoid the two the list view already
uses, which would otherwise collide at equal specificity and resolve by load
order.
