# Regression test (T1STUCK): a terminal program whose hot code tiers up to O3 -- relax-provided-
# fixture's relax-font-tier bin, a font crate's ScaledFont<F: Font> metrics (blanket impls, dyn)
# in a layout loop -- run under bare relax on a pseudo-terminal, so the boot bar draws:
# - the program ends on its own (every O3 snapshot finished);
# - no bar frame names a `tier1 locked:` take older than 2 s: the owner's item ends with its take
#   (it stayed on the last take's name for the rest of the run, 10 s and growing);
# - the last bar frame says `running`, not `compiling`, once nothing compiles (a program that
#   never presents a frame read as compiling forever).
# Linux (util-linux `script`). Run from the workspace root after
# `cargo build --release -p relax-runner --bin relax`. TARGET (default target/release).
# Prints one PASS/FAIL line per check and a last line `font_tier: N/M passed`.
