/* ──────────────────────────────────────────────────────────────────────────
   Shared Design System — common, theme-independent components
   Built on top of dark.css / light.css tokens.
   Included by tools via <link rel="stylesheet" href="../shared.css">
   (after dark.css and light.css, before the tool's own style.css)

   FORM FIELD CLASSES — use these for any new tool's inputs:
     .field-row / .field-label / .field-sub  — labelled field wrapper
     .num-input      — numeric text input (DM Sans, tabular-nums)
     .txt-input      — free-text input (DM Sans)
     .sel-input      — <select> dropdown (DM Sans, custom chevron)
     .currency-wrap  — wraps a .currency-input with .prefix/.suffix
                        unit labels (e.g. "Rp" prefix, "%" suffix)
     input[type=range] / .slider-block / .slider-head /
       .slider-label / .slider-value — sliders
   For live thousand-separator formatting on numeric/currency inputs,
   use SharedFmt.attachCurrencyInput / SharedFmt.liveFormat from
   shared.js (see <script src="../shared.js"></script>).
