/*
 * Scoped for embedding inside the footeprinting_com "spine_calculator" page
 * layout (see xsl/sty_page_layouts.xsl) and restyled onto the site's
 * Bootstrap 3.3.5 (panel/well/form-control/btn/modal/dropdown-menu/sr-only).
 * This file now only carries the bits Bootstrap has no component for:
 * the measurement/eyebrow typography, the custom paper/cover stock picker
 * dropdowns (JS-built, so their classes can't change), the big result
 * numbers, and the lead-capture overlay's positioning. Everything else
 * (buttons, inputs, selects, panel, wells, form layout, modal chrome,
 * visually-hidden helpers) is plain Bootstrap now.
 *
 * Selectors that touch bare tags (`*`, `body`, `select`, `input`, `button`,
 * `[hidden]`) stay namespaced under #spine-calculator-app so this sheet
 * can't leak onto the site header/footer/other page content.
