/*
 * Rankings tab layout: header, mode toggle + preset select, knob notes, HERO finding sentence,
 * ranked chart, chart caveat, hover strip, compact stat row + comparison rows, sensitivity
 * slope grid, footnote. Every chart is code-drawn SVG (inline elements created by
 * rankings-chart.js and rankings-sensitivity.js), so this file only handles the enclosing
 * chrome and the responsive stack.
 *
 * Round-05 hierarchy (N5-M2): the computed finding sentence is the largest text on the tab,
 * placed directly after the mode toggle above the chart. The four stat tiles now sit AFTER
 * the chart as a compact one-line-per-tile row of secondary numbers, so nothing on the tab
 * competes with the sentence except the chart itself.
