/**
 * Plugin Name: Tabi Connect ROI Calculator
 * Description: Stylesheet for the Tabi Connect ROI Calculator WordPress plugin
 * Version: 1.0.0
 *
 * Structure mirrors magnus-style.css (CSS custom properties, .result-card /
 * .result-grid / .highlight-card / .breakdown-row patterns) so this calculator
 * feels native to the existing site rather than a bolted-on widget.
 *
 * Every value below is a CSS custom property so it can be overridden from
 * Settings > Tabi Calc Style (tabi-style-settings.php) without editing this
 * file — every property used anywhere in this stylesheet has a token. A
 * subset also accept a mobile override applied at <= 768px (this plugin's
 * existing responsive breakpoint, see the media query at the bottom of this
 * file); tokens whose mobile behavior is already hardcoded into that media
 * query are marked desktop-only in the settings page instead.
 *
 * Colors, type, and geometry below are sampled from tabiconnect.com
 * (Montserrat, #0724D0 primary blue, #1B1537 navy, #F1F3FD panel lavender,
 * 16px/10px/7px radius scale, 1px #9D9C9C input borders, 0 3px 16px
 * rgba(64,64,64,.08) card shadow) so the calculator matches the parent site
 * out of the box. Override via Settings > Tabi Calc Style, or edit the
 * defaults below, if the brand changes.
 *
 * All selectors are scoped under .tabi-calc-container to avoid leaking into
 * the rest of the theme.
