/* ==========================================================================
   Kontroma — kontroma.com
   Built from "Kontroma Site v2.dc.html" + handoff/{tokens,effects}.css.

   Ground rules held from the handoff:
     - Light and dark are one design. No colour is hard-coded below the
       token block.
     - Zero corner radius anywhere. The only circles are the dots of the mark.
     - Everything flush left, including labels inside buttons.
     - 2px rules separate sections; 1px hairlines only inside a panel.
     - Archivo throughout: 400 body, 600/700 labels, 800 anything structural.

   Two deliberate deviations from the handoff, both for WCAG AA — see
   README.md "Deviations from the handoff":
     1. --k-accent-btn is used for accent fills carrying small text.
     2. --k-rule-strong is used for interactive borders.

   2. Tokens

   Light is the default and lives on bare :root, so a browser with JavaScript
   off — where no data-theme attribute is ever written — still gets a complete
   palette. Dark is applied twice: once for the OS preference (unless the
   visitor has explicitly chosen light) and once for an explicit dark choice.
   That pairing is what makes "auto" work without a value of its own.
