 # style-audit — does each cce app stand on the standard root plate and take
 # its spacing from the ladder? A conformance check, not a build step: it
 # greps the sibling app crates and prints one row per app.
 #
 #   cce-ui/scripts/style-audit            # every cce-* app beside cce-ui
 #   cce-ui/scripts/style-audit cce-mail   # one or more apps
 #   cce-ui/scripts/style-audit --strict   # exit 1 if any row is off-standard
 #
 # Columns:
 #   root      PLATE  paints PlateSpec::window / root_plate / root_at
 #             FILL   paints a full-window quad or rounded_rect instead (off)
 #             NONE   paints no window base at all (off unless opted out)
 #   ladder    how many spacing-ladder getters the app reads
 #             (root_plate_inset/padding/gap, plate_padding/gap, control_gap,
 #             the Style::root_/pane_/controls_ presets)
 #   literals  spacing consts of the app's own (const *PAD*/*GAP*/*MARGIN*),
 #             each one a number the ladder should be supplying
 #
 # Opt-outs: a crate that is not a plate by design (a transparent surface,
 # a full-bleed canvas) declares it with a line anywhere in its src:
 #   // style-audit: opt-out <reason>
 # and is listed as OPT-OUT rather than off-standard.
