A paper that reads in one language reaches the readers who read it. On Newsroom Floor a paper can open in English or Spanish, in the reader's own regional register, and a reader switches the whole paper with one tap. Names stay names and numbers stay numbers, because a story is rendered into the second language by the desk, not by the reader's browser.
A reader picks English or Spanish from the paper's own control and every page follows, the chrome and the stories alike. There is no half-translated page, because the paper serves the language the reader chose.
Each story is rendered into the second language as a real edition, so a name reads as a name and a figure as a figure. You pick which Spanish, from a neutral Latin American register to a country's own.
Open Languages, switch Spanish on, pick the register, and choose which language the paper opens in. The second-language editions fill in on their own as the paper writes, and the reader's control appears once there are two languages to switch between.
