/* ==========================================================================
   Abhi Arya — Options Tools
   --------------------------------------------------------------------------
   Same workspace design as the Trading Calculators plugin (kept as a
   separate, self-contained stylesheet with its own aaot- prefix so the two
   plugins never depend on or clash with each other): a selector (tabs on
   tablet/desktop, a native picker on phones) above one panel area where
   only the active tool is shown.

   Self-contained: this plugin doesn't assume the current theme's CSS
   variables exist (the site may change themes later), so the tokens below
   simply MATCH the current abhiarya.com design system's values today.
   Fraunces/Inter are loaded by the theme; this file only references them.

   Specificity note: this content sits inside the theme's `.prose` wrapper,
   whose rules (e.g. `.prose h2 { margin-top: 2em; font-size: … }`) would
   otherwise leak in. Every heading/text rule here is written with two
   classes so it reliably wins without !important.
