/* ============================ THEMES (palettes) ============================
   Every palette recolors the accent ramp (--teal* tokens are the app's single
   accent, used by buttons, links, focus rings, chips, the guide banner and
   active steps) and tints the sidebar, for BOTH light and dark. The neutral
   base (paper / card / ink / line) is shared per mode, so contrast and legibility
   stay consistent while each theme feels distinct. Default (no attribute, or
   "teal") uses the :root / [data-theme=dark] values above. Text on an accent is
   var(--on-accent): white in light mode, near-black in dark mode, at least 4.5:1 on
   every accent (tests/test_pr_g54_contrast.py checks every palette in both modes). */
