/* ---------------------------------------------------------------------------------------------
 * Asset Adding — light blue theme.
 *
 * The palette is taken from the AAI mark on the company letterhead (docs/CamScanner.pdf): a
 * building rising left-to-right, drawn as a navy-to-steel-blue gradient. The scan reads
 * #212B4C at its darkest through #3E5E86 to #7898B8 at the highlights; printing and scanning
 * strip saturation, so the tokens below hold the same hue family (~205-210 degrees) with the
 * saturation restored to what the mark is drawn in.
 *
 * --brand is the one to change for a re-brand; everything else here refers to these tokens
 * rather than repeating a hex. --brand carries white text at 5.4:1, which clears WCAG AA for
 * body text, so it is safe on buttons, the topbar rule and the sidebar alike.
