/**
 * The Material Design conformance audit, as a build task.
 *
 * `docs/scripts/m3-audit.sh --check` counts what the phases in
 * docs/material-design-conformance.md drove to zero -- hardcoded colours, dp literals in
 * spacing positions, bare `.clickable`, title case, untriaged `contentDescription = null`
 * -- and exits 1 when one of them has come back. It also holds two floors, for the
 * adaptive and navigation work, which regress by being *removed*.
 *
 * Wired into `check` rather than left as a script somebody remembers to run: the whole
 * point of a budget is that it is enforced at the moment the number moves, and a number
 * that is only checked when a person thinks to look is a number that drifts.
 *
 * It reads the source tree with grep and needs no gradle, no android SDK and no
 * submodules, so it is also the one part of this build that a bare CI runner can do.
