/* SLOP CENTER — the CASE tab (web/js/work/cases.js). Lives in a 720×396 box inside the 3D monitor, under the
   desk's 54 px top bar. Phone-legible: nothing you must read is under 18 px, every target is ≥ 48 px.
   Colours come from the desk's --sd-* tokens when mounted in .sd-root (fallbacks for the lab). Prefix: cs-.
   No backdrop-filter (unreliable inside CSS3D). Transient WAAPI animations never use fill. */
