What: restore CSS font-scale for Serial Monitor & Sidebar (text-ui-*) and prefer immediate WS send for Stop button.\n\nWhy: fixes visual fontScale regression and eliminates a Stop→Start race without changing header or SimulationUiProvider.\n\nScope: minimal, no behavioral changes to header/provider, no test edits.\n\nFiles changed: tailwind.config.ts, client/src/pages/arduino-simulator.tsx, client/src/hooks/use-simulation-controls.ts.\n\nVerification: full unit + Playwright E2E suites run locally and passed.\n\nNotes: preserves existing WS message flow; Stop uses sendMessageImmediate where available.
