Masume (升目) — the ruled squares of a page. A terminal substrate whose VT dispatch table, conformance matrix, terminfo entry and docs are all EMITTED from one typed sequence catalog rather than hand-written, so two faces cannot disagree about a table neither of them writes. Naturalizes the essence of Ghostty / kitty / WezTerm / Alacritty / contour rather than vendoring any of them. Theory — theory/NATURALIZE-TERMINAL.md. Name ratified 2026-08-13, opens The Page 頁.
