Mythic Masters: the Book speaks on every page, hill climb to 10/10, rounds 2+ (from #3266) #3468

Carries on from #3266 (the menu as a tome) and #3278 (the book's own voice, merged in #3453). There is no wizard: the Eldritch Compendium is a possessed book that demands we collect the earth's cryptids, like a mob boss keeping accounts. The aliens that dropped us here fled from the forces around it, not from the book itself. More lore comes later, from the owner.

Goalpost: the Book speaks on every page

The score is how many of the ten menu surfaces carry the Book's hand (a demand or a margin line in Covered By Your Grace, signed "the Book" where it makes a demand) and its rust thumbprint. Each one has to say something true for that page, not just repeat the same line.

Score: 4/10 (target 10)

What is in the code

• apps/mythic-masters/src/demand.ts: demandOf(journey) (the ledger: "Item n", names what you have met, describes what you have not) and thumbAt(n) (where the thumbprint lands).
• src/page.ts: thumb() presses one thumbprint on each page book().show() opens.
• src/tome.css, end of file: .demand (red hand over the printed page) and .thumb.

Next, one PR per round

1. Margin-note voice guide in apps/mythic-masters/ (a short list of rules and about 20 example lines: terse, boss-like, funny, never explains the forces). Every later line follows it. (Carried over from Mythic Masters: the menu is a wizard's tome (and the book is secretly his contacts list) #3266.)
2. The result note: the Book reacts to a bind ("Item 6. Received.") or a loss.
3. The starters sheet and the bestiary deck get a demand or margin line.
4. The world's toasts in the Book's hand when you bind something or clear a section.
5. Settings: one dry margin line.

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

• 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 into something else, or go?
• Depth mechanics for the demands (the owner said they will add them over time). One option from Mythic Masters: the wizard himself (handwriting, name, one recurring stain) #3278 was 1C: the hand gets more scrawled the longer a demand goes unmet.
