// Scope: exactly what src/ui-touch + the helpers it pulls in need, no more. Strings,
// Print and Stream are the REAL arduino-esp32 2.0.17 sources (web/compat/arduino/,
// LGPL-2.1, unmodified), so String formatting behaves like on the device. Time comes
// from a monotonic clock started at boot. GPIO is a no-op (there are no pins).
//
// Must stay plain C/C++17 + POSIX: the same header builds under Emscripten (phase 2).
