/* ══════════════════════════════════════════════════════════════════
   PARTNERSHIP — EARNINGS CALCULATOR
   The "grow / how it works" band and the interactive calculator.
   -------------------------------------------------------------------------
   THIS COMPONENT CARRIES NO PALETTE OF ITS OWN. It reads the landing-family
   token layer the rest of the page is built from (landing.css declares it on
   [data-theme]; it loads after theme.css and paper.css), so the calculator is
   the platform's colour in BOTH themes and a token change lands here for free.
   The card recipe below is .sw-panel's — border --border, ground
   --bg-card-solid, depth --shadow-card + --edge-top — so this card sits at the
   same height as every other card on the page.

   The only non-token values are the per-tier accents, which arrive from the
   admin's partnership-tier config as an inline --pc-tier-accent /
   --pc-seg-accent and are fed through the platform's local-accent helpers
   (--c → --tint-c / --tint-c-edge / --ink-c). See the accent-carrier block at
   the END of this file: it is load-bearing, not decoration.

/* ── Accent carriers ─────────────────────────────────────────────────
   A tier's colour comes from the admin's partnership-tier config, handed to the
   page as an inline --pc-tier-accent / --pc-seg-accent. Both are mapped onto the
   platform's local --c.

   Redeclaring --tint-c / --ink-c here is NOT optional. landing.css defines them
   on [data-theme] (<html>), and a custom property's value is substituted where
   it is DECLARED — so by the time those helpers reach these elements var(--c)
   has already been resolved to the ROOT accent, and every tier would come out
   russet. landing.css documents exactly this trap for its own chapters; the fix
   is the same one it uses: declare the helpers on an element that carries the
   local --c. The light pair below mirrors landing.css's numbers (10% / 26%
   tints, ink mixed 40% into the dark ground) so a configured accent stays
   readable in either theme rather than only the one it was picked for. */
