/* Brand mark — shape only (matches assets/logos/biometrix-mark.svg), used as
   a mask and painted with a CSS gradient. The color comes from --accent-500
   / --brand-500 rather than the file's own fill, so the mark switches with
   the theme automatically — no JS, no per-page duplication.
   Inlined as a data URI rather than referencing the file by url() — an
   external mask reference is unreliable when the page is opened directly
   (file://) instead of through a server, and this removes that dependency
   entirely. mask-mode is forced to alpha so browsers that default SVG masks
   to luminance still render the full shape instead of a dimmed one. */
