/* ============================================================
   preetam.org v2 — Cobalt
   Light on :root. Dark overrides tokens only, twice: once for the
   system preference, once for the explicit toggle.

   Layout direction: "Shelf" — screenshot tiles on a shelf grid,
   generous whitespace, one clear action per tile, one accent band.
   No gradients, no shadows: a hairline border does the separating.

   Order of this file:
     1. fonts
     2. tokens (three theme states)
     3. base: reset, body, type, focus, layout primitives
     4. components
     5. reduced motion
   No component rule may contain a hex literal. Colour comes from
   tokens only, so a theme change is a token change.

   about a quarter of a phone screen, permanently.

   Below 30rem it keeps the two jobs a sticky header has to do on a phone,
   identity and getting around, in two tight rows:

     row 1  brand, and the theme toggle at a full 36px tap target
     row 2  the nav, on one line, scrolling sideways inside itself if the
            links outgrow the width -- never wrapping into a third row

   It holds up to 40rem, which is the width where the one-row header starts
   fitting again, so there is no band of screens left standing on a tall
   wrapped header.

   The "Hire me" button steps out at this width. It is a shortcut to the
   hire-me band on the same page, the nav's own Contact link covers the same
   intent, and it was the single largest thing in the header. Hiding it buys
