   Third Rock Wealth · tool-cta.css
   Styles for the per-tool CTA partial mounted by tool-cta.js into
   the [data-anim="cta"] slot on every calculator tool page.

   Two design choices that matter:

   1) The CTA is a properly DEFINED PANEL — solid border in the
      tool's accent colour, faint accent-tinted background, the
      rounded surface treatment the rest of the page uses. Sits
      INLINE inside the instrument flow, right after the chart,
      before the "how to read this tool" guide — peak engagement
      moment.

   2) Each tool's signature accent colour drives the panel —
      border, background tint, kicker text, button, focus ring,
      link underline — via color-mix(in oklab, var(--accent),
      transparent). Each tool's body[data-tool="<x>"] already sets
      --accent + --accent-bright, so the rules are palette-agnostic.

   The result-panel jump link (.tk-readout-jump) is a small mono
   button that sits inside each tool's result panel next to the
   final-number figures. Clicking it smooth-scrolls to the main
   CTA below.
