   compound-interest.theme.css — TFSA / RRSP / non-registered comparison

   Loaded AFTER styles.css and tool-base.css. Wrapper is
   `<div class="tool-app ci-app">` — `.tool-app` is what pulls in the shared
   print invariants; this file owns everything else.

   VAR INDIRECTION (same pattern as the other three themes, on purpose)
   The block below re-declares the TOOL's own variable names on `.ci-app` and
   maps each onto a site token. tool-base.css overrides those same names inside
   @media print. Do not "simplify" it by inlining site tokens into the rules —
   the indirection is what lets the print block re-theme the whole tool by
   changing ten values.

   DO NOT re-declare here what tool-base.css already owns in print: the body
   reset, `color-scheme: light` + the ten light vars, `.wrap`, the `.print-only`
   masthead, the `.grid` flex fix, the page-break atoms, or print-color-adjust on
   `.chart-track`/`.chart-fill`. This file adds only what is specific to this
   tool — and one thing tool-base explicitly does NOT cover: the SVG chart's own
   strokes, which are a different class and do not inherit its
   print-color-adjust rule.

   TOUCH: this tool shipped WITH the 44px pass rather than joining the debt pile
   the other three carry. Sizes are `px`, never `rem` — styles.css:1142 drops
   `:root { font-size: 15px }` at 480px, so a rem-based 44px target renders 41px
   on exactly the phones that need it most.
