/* calc-pack widget.css — build 5
 *
 * One product look. Build 4 kept priceguide's screens and flow — landing,
 * photo-tile service picker, "X of Y" question steps, lead gate, result
 * with a range and a per-service breakdown — and this build keeps every
 * one of them. What changes is the CHROME, which now comes from the
 * RuufPro estimate widget (roofer-template EstimateWidget.astro): one white
 * card, one radius, one grey scale, one button system.
 *
 * The shape, in one paragraph: a single white card, 720px at its widest,
 * centred on whatever page it is pasted into. A hairline accent progress
 * bar under a small "X of Y" label. Left-aligned headings on every working
 * screen and one centred landing screen. A grid of photo tiles that wear
 * the card's own border and radius. An action row hairlined off the bottom
 * of the card, Back on the left and the primary on the right.
 *
 * ONE radius, everywhere:
 *   --calc-radius: 10px   card, tiles, inputs, buttons, chips, panels
 * The only round things left are icons, not controls: the tile's selected
 * mark. An icon is not a control, so it sits outside the radius rule — the
 * same carve-out the reference makes for its own check badge.
 *
 * The owner edits colors and copy through the `brand` block (see README).
 * An embed can override the same tokens per-instance:
 *   <div class="calc-widget" style="--calc-accent:#0f766e">
