When only the closing block moved to page 2, the page-1 deficit was shared across every gap, including the closing block's own gaps, which cannot help page 1. Page 1 then came out a few points short and the totals spilled over with the closing block. Monolith and Cobalt Stripe now squeeze only the page-1 gaps in that case, as Marble and Highlighter already do.
Monolith's flow notes block could start in the last few points of a page and be cut into zero-height lines. It now holds 70 pt of room under its label first, as Marble does.
Adds tests for both cases (they failed before the fix) and notes in the template specs. Fingerprint goldens and thumbnails are unchanged.
