/*
 * FAQ — sticky sidenav + native <details>/<summary> accordion.
 *
 * Pure CSS / zero JS: <details> handles open/close natively with
 * full keyboard accessibility. The amber `+` toggle rotates 45° to
 * a `×` when the section is open via `[open]` attribute.
 *
 * Mobile sweep: at <=900 the sticky sidenav drops above the content
 * as a compact list (no longer sticky).
