bump: patch type: fix Text keys below a row, padding, and tr's cast. A @Text Key in a record nested in a registry row (and in each item of a list of them) is filled with its derived key, <registry>.<row>.<field>.<i>.<field>, as a top-level one is, and a @Text []Key a row leaves out takes <...>.0, .1, ... for as many as the source .po has - so no .lres spells a key. field: null is no text. trf / trn's trailing "" arguments are padding and not counted against the English's holes. And string(x) of a string or a Key is no allocation to the escape analysis: it is x itself, so a tr(key) that returns it passes arena strict (a template's lone hole still copies).
