/* Brand tokens: BClear Aligner (light theme only).
   Source: the bclearaligner.com Elementor global kit: primary #00A7E1, text #333E48,

   Contrast: #00A7E1 is 2.8:1 on white, so it is used for fills, icons and decoration
   only. Text and links use brand-700 (6.0:1 on white), dark labels on a sky-blue fill
   use on-brand (5.9:1), and primary buttons use the action blues with white labels. */
