/* ==========================================================================
   akash.page: one hand-written stylesheet. No framework, no build step.

   The look is a founder's field notes: dot-grid paper, ballpoint-blue ink as
   the one action colour, and six highlighter markers (lemon, pink, mint,
   tangerine, violet, cyan) for topics and drawings. Headings are Bricolage
   Grotesque, text is Inter, small print is JetBrains Mono.

   It is onemana.dev's sibling, not its copy. It keeps the family bones
   (Inter, the ring motif, graphite dark mode, one action colour) and has its
   own inks. The blue comes from the impossible triangle Akash has always used
   as his mark. Every colour below is a token, and every pair that carries
   text passes WCAG AA in both themes.
   ========================================================================== */
