/* JKST Note site — one stylesheet, no fonts loaded, no third-party requests.
   Colours are the app's own tokens (quick-capture-notes-app/designs/brand/palette.md):
   neutrals on hue 250, and the brand azure is accent/jot.

   One deliberate divergence: --secondary is text/secondary (#6e757d) in light mode but
   text/tertiary (#8c939a) in dark. Measured on these grounds, text/secondary dark
   (#6d747b on #08090a) is 4.21:1 — under the 4.5:1 floor for normal-size body text, and
   3.86:1 on the raised surface. Tertiary reaches 6.41:1 on the dark page while secondary
   reaches 4.59:1 on the light one, so one token per mode clears AA on both. */
