/**
 * Front-page slider styling.
 *
 * Single overlapping viewport: every slide stacks in the same box; the active
 * one is shown, the rest are hidden from layout and assistive tech. An
 * aspect-ratio container reserves height so unloaded images cause no layout
 * shift. Caption "over" gets a contrast scrim (the audience skews older; high
 * contrast is a stated principle). The caption feature is provisional — see
 * tasks/homepage-slider.md — and is kept cleanly separable.
