Tik op een van de drie binnenmodules zet die bovenaan de lijst (de overige twee behouden hun onderlinge volgorde) en vergroot alleen het temperatuurgetal van 50 naar 92px. Nogmaals tikken op de bovenste (vastgezette) module zet 'm weer los. Puur client-side, geen nieuwe API-velden: state.pinnedRoomId + de pure functie pinRoom() (met tests) in format.js. De keuze overleeft de 5-minuten-verversing, reset bij een volledige herlaad. Servicewerker naar v6. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
