Mythic Masters: the Book's hand, hill climb to 10/10, rounds 8+ (from #4034) #4145

Carries on from #4034 (rounds 6 and 7, PR #4144), which carried on from #3912, #3854, #3472, #3468, #3266 and #3278.

Where it stands

With PR #4144, all ten menu surfaces carry the Book's hand and thumbprint, so the old goalpost is full: Score 5/10, which is where the owner's halving (2026-11-05) caps it. Going further needs a new goalpost.

Owner's call (ask, don't guess)

• The new goalpost. One option: how many surfaces react to what you did (your ledger, your last fight, your settings) and not only to the page. Another, from Mythic Masters: the wizard himself (handwriting, name, one recurring stain) #3278 option 1C: the hand gets more scrawled the longer a demand goes unmet.
• Mythic Masters: the menu is a wizard's tome (and the book is secretly his contacts list) #3266's late-game secret (the book is a wizard's contacts list) came before "there is no wizard". Does it stay, change or go? It is still marked on hold in docs/MARGIN-NOTES.md.

Known gap to fix in a round

• On the very first bind, the Book's talk (the bind beat in book.ts) opens over the new world toast, and the toast fades behind it. Hold the toast until the talk shuts.
