+-- Board support for Cortex-M: startup, memory layout, a semihosting console,
+-- and the runners that reach an emulator or a debug probe.
+--
+-- ⭐⭐ ONE PACKAGE, TWO ENVIRONMENTS — AND SINCE 0.2.1, THREE FEATURES.
+--
+-- A board reached through an emulator and the same board reached through a
+-- debug probe differ in the argv of their runners and in NOTHING else: the
+-- linker script, the startup code, the memory map and the exported module are
+-- the same board. Publishing two packages to vary four strings would duplicate
+-- all of it and let the copies drift. So the environment is a FEATURE, and the
+-- consumer selects it where it selects everything else:
+--
+--     mcpp run                        # the emulator
+--     mcpp run --features hardware    # the board, over a debug probe
+--     mcpp run --features libc        # with a C library
+--
+-- ⭐ `mcpp run` IS THE WHOLE OF THE COMMON CASE, ON EITHER. On a device,
+-- running a program means writing it, resetting, attaching to its output and
+-- reading its exit status — ONE command, not several. So that is the DEFAULT
+-- runner in both environments, and the command a developer types does not
+-- change when the board arrives. `flash` and `serve` are named exceptions, and
+-- the engine knows neither name.
+--
+-- ⚠️ EACH ENVIRONMENT BRINGS ITS OWN TOOL, ON THE `run` TIER. `qemu-arm` under
+-- `[feature-xlings.emulator]`, `probe-rs` under `[feature-xlings.hardware]`,
+-- both `when = "run"` — so a consumer downloads exactly what the feature they
+-- selected needs, and a CI job that compiles firmware and never flashes it
+-- downloads nothing at all. Requires mcpp 2026.9.4.2.
+--
+-- ⚠️ AND THE BOARD SETS THE THREAD POINTER, which is what makes `libc` work.
+-- picolibc reaches `stdout` through thread-local storage, and a freestanding
+-- image has none until the startup file sets one. Measured without it: a
+-- `printf` program linked cleanly, ran, printed NOTHING and hung. There is no
+-- diagnostic for that state; the only evidence is silence.
