/*
 * Section type: Sekmeli Cihaz Seçici (Tabbed Device Selector).
 * Reuses shared classes from main.css (.sembo-container, .sembo-kicker,
 * .sembo-section-heading, .sembo-text-link) — only section-specific classes
 * are defined here, all scoped under .sembo-tabs-sel-*.
 *
 * The tab interaction is pure CSS: three visually-hidden (but focusable) radio
 * inputs are toggled by labels styled as tab buttons, and the general sibling
 * combinator (~) shows the matching panel based on which radio is :checked.
 *
 * Because this section type can be placed more than once on a page, every
 * instance gets its own dynamic id/name attributes (see inc/sections/tabs-selector.php),
 * so these selectors CANNOT target fixed ids like the old #hp8-tab-1. Instead,
 * the Nth radio input (counted structurally via :nth-of-type, independent of
 * its id/name) is paired with the Nth panel (also counted via :nth-of-type)
 * inside the panels wrapper — see the "Panel pairing" block below. This works
 * for any instance id and for any number of instances on the same page.
 *
 * No JavaScript anywhere in this section.

/* ---------- Panel pairing (the trickiest part) ----------
 * Panels are hidden by default. To reveal the panel that matches the checked
 * radio WITHOUT relying on ids (which are now dynamic per instance), we pair
 * "the Nth radio input, counted structurally" with "the Nth panel, counted
 * structurally" using :nth-of-type on both sides of the same selector chain:
 *
 *   .sembo-tabs-sel-input:nth-of-type(N):checked
 *     ~ .sembo-tabs-sel-panels .sembo-tabs-sel-panel:nth-of-type(N)
 *
 * - `:nth-of-type(N)` on the input counts only <input> siblings among the
 *   tabset's direct children, in source order — so input #1/#2/#3 map to
 *   N=1/2/3 no matter what id or name they carry.
 * - The general sibling combinator (~) reaches from that input past the
 *   labels block into the panels wrapper.
 * - `:nth-of-type(N)` on the panel counts only sibling <div class="sembo-
 *   tabs-sel-panel"> elements inside the panels wrapper (they are the only
 *   children there, all <div>s), so panel #1/#2/#3 also map to N=1/2/3 by
 *   pure source order — again with no id dependency.
 * - Because N is matched on BOTH sides of the same rule, input N being
 *   checked can only ever reveal panel N. This is fully instance-agnostic:
 *   the same three rules work correctly for any section id, and for multiple
 *   instances of this section type on one page, since each instance's own
 *   input/panel pair only ever affects descendants within its own
 *   .sembo-tabs-sel-tabset.
