/**
 * Mortgage Calculators: Custom Styles (UIKit companion)
 *
 * UIKit handles layout, forms, cards, buttons, and responsive.
 * This file covers ONLY what UIKit doesn't provide:
 *   1. Accent color theming via --mcalc-color
 *   2. Range slider thumb
 *   3. Toggle switch
 *   4. Result hero display
 *   5. Honeypot hiding
 *   6. Focus-visible ring on accent-colored buttons (inline background
 *      can suppress UIKit's default focus outline on some browsers)
 *   7. uk-hidden-visually safety net (UIKit provides this, but a local
 *      copy makes the plugin work on themes that strip UIKit utilities)

 * render the form and results panes side-by-side. The widget then
 * either overflows or compresses unreadably.

 * Fix: when the calculator's own container is below ~700px, force the
 * panes to stack regardless of viewport. We name the container "mcalc"
 * (set up at .mcalc { container-type: inline-size; container-name: mcalc; })
 * and query its inline-size.
