/*
 * Advanced filter toolbar — the shared advanced-filter strip and the
 * `.multi-filter` multi-select component that lives inside it (ISH-261).
 *
 * Before this file, the toolbar pattern existed as three hand-copied blocks in
 * brokers.html, analytics.html and map.html, each with its own inline <style>
 * copy of the same ~180 lines. ISH-261 needed a fourth consumer (the Sales
 * Pipeline board), so the block was factored out here rather than pasted again
 * — the same move css/stage-colors.css made for the stage palette.
 *
 * The values are brokers.html's, which is the canonical look the other pages
 * were copied from. One intentional difference: `.filter-clear-btn` sets
 * `align-self: center` here, because brokers.html's `flex-end` base was already
 * overridden to center by an inline style on the element itself — center is what
 * that page actually renders, so it is what the shared file declares.
 *
 * Consumers today: sales-pipeline.html, sales-pipeline-report.html (ISH-497 —
 * its geography scope bar's Region/Market/Submarket filters). brokers.html,
 * analytics.html and map.html still carry their own copies; migrating them is
 * deliberately left out of ISH-261 (three heavily-used pages, no behavior
 * change to show for it) and tracked as ISH-444. When you migrate one, delete
 * its inline block rather than leaving both — a page linking this file *and*
 * declaring `.mf-trigger` locally is how the pre-ISH-353 stage palette drifted.
 *
 * Depends on the page's own :root tokens: --red, --border, --border-light,
 * --page-bg, --text, --text-secondary, --text-label, --radius. Every page in
 * this app declares all of them.
 *
 * The markup contract this styles (see sales-pipeline.html for a full example):
 *
 *   .filter-btn                 toggles [hidden] on .filter-strip
 *   .filter-clear-btn           resets every filter at once
 *   .filter-strip > .filter-row.row-spread > .filter-group
 *     label + .multi-filter
 *       .mf-trigger             shows placeholder, or .mf-trigger-chip per value
 *       .mf-dropdown[hidden]    .mf-search + .mf-list > .mf-option / .mf-empty
 *
 * js/shared.js's createMultiFilter() drives that markup — it owns the classes
 * `has-value`, `selected`, `mf-empty` and the `aria-expanded` toggle, so don't
 * rename them here without changing it too.
