   SwarLekh — "Manuscript & Dawn" visual language

   Warm paper + iron-gall ink, saffron (accent) and indigo (melody) — the two
   colours of a riyaz notebook at first light. System fonts only, zero external
   assets. Drop-in replacement for style.css: every selector contract from the
   original stylesheet is preserved, including every CSS custom property that
   js/main.js reads for the contour canvas:
     --card --grid --grid-strong --sa-line --pa-line --muted
     --accent --accent-soft --contour --komal --text   (+ --indigo, used
     inline in index.html's contour legend).
   Dark mode overrides the same tokens via prefers-color-scheme.
