FX.127 Website footer: the language picker sits in the Community column under a rule; Save is a small button that shows once the pick changes

Owner 2026-11-07 (screenshot): the footer language picker moved from the notes strip into the Community column, under a rule like the one above SuperCad Studio in Apps. The Lab tag sits beside the heading. Save is a small button that appears only after the pick changes (site.js; without JavaScript it always shows). Files: core/components/footer.inc, core/components/site-lang.inc, assets/css/site.css, assets/js/site.js. Still lab only (can_lab). Then (same day): pinned to the bottom of the Community column (.tb-community flex column, margin-top auto). Community column gets the spare width from 1100px (columns .75/1/1/1.25; equal below).
