/* MIFilterSidebar — sidebar version of Apollo's filter UI (Phase C).
 *
 * Renders as a single Side.Section's child via app.js's viewSidebarSlot.
 * The OlympusShell sidebar is 280px wide (collapsible 48px); these
 * styles assume the section has ~256px content width after side
 * paddings. Sub-sections are collapsible (button + body) for default
 * vertical density.
