/* ============================================================================
 * Compliance — kill-chain cascade, tenant strip, tactic rows, tenant×axis
 * matrix, and the right-side drilldown rail.
 *
 * Two-column layout owned by ``.fw-killchain-grid`` (cascade + rail at
 * desktop widths, stacked on narrow viewports).  The matrix subsection
 * covers both progression frameworks (MITRE-style worst-reached) and
 * parallel-measures frameworks (AWIA / CISA grade-glyph cells).  MITRE-
 * specific rail chrome (sparkline, phase-card drill, selection states)
 * lives in data/compliance/mitre/static/rail.css per Phase 15 §9.
