/**
 * Accessibility toolbar + back-to-top for resume.berezawp.com
 * Ported from the prismaticflowers.com widget 2026-07-30 and re-themed.
 *
 * PORTED, NOT PASTED. Four defects in the source were fixed on the way over
 * (memory: feedback_porting_a_component_means_testing_it_not_pasting_it):
 *   1. 29 inline onclick handlers -> data attributes + one delegated listener,
 *      so a stricter CSP later cannot silently disarm every control.
 *   2. `font-size: calc(1em * S)` on every element compounded once per nesting
 *      level (17.5px became 560px on one site). Scaling happens ONCE at :root here.
 *   3. alert() on reset -> an aria-live status region.
 *   4. Floating furniture: ADA sits bottom-LEFT, back-to-top bottom-RIGHT, and
 *      nothing else on this site is pinned, so they cannot overlap each other.

/* Scaling is applied ONCE here. Never re-multiply per element.
 *
 * Scaling :root alone was NOT enough on this site and shipped as a dead control
 * until a click test caught it: style.css sets `body { font-size: 16px }` (14px
 * under 480px), and that px declaration overrides the inherited root size, so
 * every <p> stayed at 14.0px while the slider moved. Headings use rem and would
 * have scaled, which is exactly why a spot check on an <h1> would have passed.
 *
 * So body is re-declared here against a CONSTANT base times the scale. The
 * multiplier still lands exactly once, so nothing compounds through nesting.
 * The breakpoint below mirrors style.css:604 - keep them in step. */
