 * Tooltip — the "i" info pill on each comparison row.
 *
 * Earlier this block referenced --color-text-strong and --color-bg-alt, which
 * are NOT defined in lib/app.css (the canonical set is --color-text-primary
 * / --color-bg-surface-alt). The undefined tokens collapsed to nothing, so
 * the tooltip rendered as a transparent box with no visible text. Fix is to
 * point at --mm-navy / #fff and the mm-* token set the rest of the chrome
 * uses.
 *
 * Tooltip now positions ABOVE the icon with a small downward arrow so it
 * never gets clipped by row overflow when the row is near the bottom of the
 * card. Keyboard users get the same state via :focus-visible.
