/* ── Tool shell ────────────────────────────────────────────────────────────
   Layer 2 of the tools architecture. Sits between portfolio chrome
   (Layer 1: top nav, loading screen, fonts) and tool-specific UI
   (Layer 3: e.g. calculator-core.css + house-calculator.css).

   Provides shared chrome for every utilitarian tool:
   - Slim hero (~25vh) — title + one-line value prop, no scroll-fluff
   - Byline footer — single-line attribution + cross-links to sibling tools

   Inherits portfolio CSS variables (--color-text, --color-light,
   --color-border-light, --color-blue, --animation-primary) from
   styleguide.css. Tool-specific tokens (--bg, --text, --accent) are
   defined inside .calculator-section etc. — this file does not touch them.
