Layer-2 Inter-Chapter Transitions — the Ch 72 to Ch 77 and Epilogue traveled through-line

RE-DERIVED 2026-07-27 against the live v3 spine (the endgame-renumbering sweep, lane 3). This document was authored at the RR-FINAL window against the PRE-v3 finale topology, and two of its worst bullets were spot-repaired earlier the same day; this pass re-derives the WHOLE document — every chapter-number assertion, the war's window, the antagonist arcs, the travel medium, the vril curve, the companion and familiar ledgers, and all six seam descriptions — from docs/spine/CH_72.md through CH_77.md and CH_EPILOGUE.md (their Entry-header, Continuity-anchor, End-state-carry-forward, and Seam-state-diff blocks), the live T0_Chapter_Index and T0_Boss_Encounter_Registry rows, and the amended HL_0035 and HL_0108 rows. The structure is kept; the facts are corrected. What changed at the topology level: the Realm War is no longer three chapters ending at Ch 73 — it is ONE chapter, Ch 75, in three movements; Ch 72, Ch 73, and Ch 74 are the last three Realm-Road otherworlds (Naraka and Meru, Annwn, Yggdrasil), and Ch 74 is the crossing home; the patriarch is named and resolved at Ch 76, with the father encounter folded in as that chapter's second phase; and the waterfall is a single node, Ch 77, whose approach is compressed into its own opening. The pre-v3 to live numbering map is recorded in the header note of docs/spine/range_reviews/RR_FINAL.md.

Story Spine Layer-2 add-on. This realizes docs/TRANSITION_TREATMENT.md Layer 2: the connective bridges between chapters — how the protagonist arrives from the previous chapter and departs toward the next — held separate from the chapter bodies because in the 3D build these are their own arrival and departure sequences, not chapter-body prose. It is authored with the whole finale range in view, since the window's defining movement — the last three otherworlds of the Realm Road giving way to the crossing home, the realm's own war, the double reckoning of the Two Courts, the summit reveal, and the closing bookend — is tunable only at range scale. It continues from docs/spine/transitions/TRANSITIONS_CH62_71.md, with one caution recorded honestly: that document has NOT been re-derived against the v3 spine (it still carries the retired Pohljar, Tiamarath, and Maatherion realm names and the pre-fold Realm-War phases at Ch 71-72), so its seam content is not treated as current here. The live Ch-71 exit used below is taken from the Ch-71 seam state-diff block in docs/spine/CH_71.md itself.
