/* =====================================================================================================================
   LL-LIBRARY (2026-10-09): the look of the shared client (ll-library.js): the heart, the save button, the "Save to"
   sheet, the question asked first and the toast. Only .lll-* lives here. Code/my/README.md, "The shared client".
   THE RULES IT KEEPS (design-system.md, site-art.md): dark; #ef4444 the accent; #c41e3a only as a fill; glows are
   drop-shadow or gradients; drawn icons; a heart sits at a picture's top right, never its bottom-right corner (the
   mark's); every picture whole; reduced motion: no pop, no slide, fades of 150 ms or less.
