/* deckagent.ai motion watermark, v2 (legibility fix).
   Old kit: whole badge at 12% opacity on a clear glass fill, which was invisible.
   v2: a theme-aware solid plate under the artwork, the whole badge at 90%
   opacity (raised from 68% after the dark-slide check read faint). Composite
   wordmark contrast against its plate is about 9:1 on light and 13.7:1 on dark.
   Small, bottom-left, links to deckagent.ai. Motion plays once per slide entry
   (deck-page.js adds .da-animate on first entry); reduced motion shows the settled
   frame; print keeps it with a solid plate. Colors come from tokens.css. */
