   Sits in the content well so it tracks the grid, then bleeds off the right

   The bee is the fallback and the arms are the override, scoped to the
   `narpo-has-arms` body class rather than to `--mn-arms` alone: that is the
   pattern every other arms placement follows, and it means the band still
   carries a device if the artwork is ever cleared in Site Settings.

   The arms are drawn as a MASK, not as a background image. The artwork is
   full-colour heraldry whose helmet and chequered border are opaque white —
   laid over slate at watermark opacity those read as bright patches rather
   than as one device. Masking a flat colour through its alpha gives the
   silhouette the bee had, in the same ink. Heraldry is also never tilted,
   so the arms drop the bee's -8deg. */
