/* ---- Lab Gpt design tokens ----
   palette sampled directly from the approved avatar/banner/post art (PIL histogram):
     mint      #cae2bc  (lab wall / page field)
     mint-dark #a9c99a  (mint, deepened for contrast)
     grey      #82847e  (bench / shelving)
     grey-dark #4e4f4e  (storage room shadow)
     cream     #fffef5  (mouse body / paper)
     ink       #17181b  (outlines)
     teal      #c8ebdc  (beaker liquid) -> deepened to #3f9c82 for the interactive accent
     peach     #ffcab3  (clipboard paper / ears) -> used for the stamp / tag accent
   type: Crimson Pro (research-report serif, headings + log copy) + JetBrains Mono
   (timestamps, counters, the CA - real case, unambiguous 1/l/0/O).
   spacing scale: 8 / 12 / 16 / 24 / 32 / 48 / 64px. radius: 3px (paper-corner, not app-rounded).
   motion: one idiom - a slow blink-cursor caret on the log's newest row. */
