 - Keep clear space around the mark equal to at least 9% of its width.
 - Use the supplied assets rather than cropping or redrawing the symbol.
 - Do not add an enclosing circle, glow, drop shadow, or decorative state lines.
-- Preserve the cobalt-to-cyan direction and violet checkpoint.
+- Preserve both arrow directions, the central verification check, and the violet checkpoint.
 - Use the full project name in adjacent text; the mark does not contain a monogram.

 The README cover remains a separate editorial illustration. The social preview uses the mark as
 part of a composed 1280x640 sharing card and should not be substituted for the README cover.
