/* Shared platform chrome stylesheet.
 *
 * Every proposal tool built with a dark/light calculator UI (design tokens,
 * panels, currency bar, model tabs, wizard modal, changelog modal, theme
 * toggle, discount/escalation approval modals) had its own copy of this same
 * ~220-line block, hand-copied tool to tool. This is that block, extracted
 * once - link it with <link rel="stylesheet" href="/shared/platform.css">
 * instead of pasting a new <style> block into a new tool.
 *
 * What this file deliberately does NOT own: page title, hero copy, and any
 * layout specific to a single product's inputs (that stays in the tool's own
 * <style> block, scoped to that product's own classes/ids).
 *
 * --orange is BUI's brand accent by default. A tool for a different brand
 * variant can override the handful of --orange*/--accent* custom properties
 * in its own <style> block, after this stylesheet is linked.
