/*
 * The translator page /translate (phase PN1 of docs/translator-plan-2026-10-13.md).
 *
 * The layout of the mockup mockups/translator-2026-10-13: two panes on a computer (variant A), one
 * column on a phone (variant C), aligned rows on demand (variant B). It styles the server form, so
 * the page looks the same with and without /assets/translator.js; the parts the script adds use the
 * `.tr-js` classes. Colours come from the shared shell's variables, so the light and dark themes and
 * the theme switch keep working; the soft tints are mixed from them where the browser can.
