/* =========================================================
   measure.css — /measure tablet surveyor
   ---------------------------------------------------------
   Consumes the styles.css :root tokens (--ink/--line/--bg-alt/--accent).
   CAD-professional flat style: sharp corners, hairlines, no shadows.
   Touch targets >= 44px everywhere a finger lands (goal §12).
   Layout: top bar / left palette / stage / right properties panel;
   on tablet portrait the right panel becomes a slide-over so the
   canvas keeps the full width.
