/*
 * Floating Accessibility widget — user-facing display/reading/motion controls, separate from
 * pto-a11y.js (which auto-wires label/input associations at render time; a developer-facing
 * markup fix, not a visitor-facing tool). Every effect here is opt-in and OFF by default; nothing
 * in this file changes how the site looks until a visitor turns something on from the panel.
 *
 * Filter-based Display modes (High/Dark contrast, Grayscale, Invert, Saturation, Dim images) are
 * computed and written into #pto-a11y-dynamic-style by pto-a11y-widget.js rather than as static
 * rules here, since more than one of them can combine into a single `filter` value at once (CSS
 * can't merge two independently-toggled classes' own `filter` declarations — the later one just
 * replaces the earlier one) — see that file's updateDynamicStyle().
