/* ==========================================================================
ADITSY — Design System, "Yestalgia" theme
Sun-bleached, colour-block, sticker-pop retro. Cream canvas, thick ink
outlines, hard offset shadows, and a warm sunset gradient standing in
for the old dark-void thrust accent. Same tokens, new mood: 80s poster
over launch-pad.

Same token names, inverted mood: warm cream flips to a near-black,
coffee-brown void; the thick ink outlines and offset "sticker" shadows
flip to a light stroke so cards still read as cut-out and pinned down,
just under a different light. Accent hues are untouched — they were
already saturated enough to hold up on a dark ground.

the OS preference decides ("System" in the theme switcher). */
