The engine now owns the words it puts on a page that the author did not write (ADR-0034). `internal/render/chrome.go` holds the phrase table, Gregorian month names and decimal digits per language, keyed phrase-then-language so both forms sit side by side and a half-translated row is visible while reading. Templates reach it through `t`, `num` and `day`, registered before parsing so a site override's blocks may call them too. The reference theme stops hardcoding English: "Newer", "Page 2 of 2" and every date now come from the table, while `datetime` attributes stay ASCII because a parser reads them. Authored text gets goldmark's typographer and nothing else — quotes, dashes and ellipses smoothed, code spans untouched because it works on the parsed tree. It is a parser option rather than a function over a page, so the transforms counter does not move; state.md now says why, so the next reader does not miscount. Deliberately absent: relative dates, which need a validity window that only the cache entry will have, and body widow prevention, which cannot be done safely by a pass over rendered HTML.
