/* Living Trust Express — Brandcore sales deck
   "Paper & Ink": ivory paper slides and deep ink-navy slides, accented only with
   the green and blue of the client's own mark. One stylesheet, no override layers.

   Every slide is laid out on a 1640 x 920 canvas and scaled by --u (1 canvas px),
   so the composition is identical at 1920x1080, 1366x768 and in print.
   Text colours are tokens per theme; every pairing below meets WCAG AAA (>= 7:1). */
