/* Twoslash — interactive TypeScript type hovers, inline errors, ^? queries and completions
 * on ```ts twoslash code blocks. Rendered at build time by Shiki + @shikijs/twoslash (see
 * aardvark/twoslash.py); this file styles the markup that the @shikijs/twoslash *rich*
 * renderer emits. Loaded only on pages that contain a twoslash block (base.html gates it on
 * page_has_twoslash).
 *
 * The structural rules below are vendored from @shikijs/twoslash's reference style-rich.css;
 * the popover / docs / border / shadow colors are driven entirely by the --twoslash-*
 * variables, which we remap onto aardvark's --aardvark-* tokens — so the popovers track the
 * site theme and flip on the dark scheme automatically, with no separate dark structural
 * block. Token colors come from Shiki's dual themes (see the .shiki rules).
 *
 * UPGRADE NOTE: two emitted class names couple to @shikijs/twoslash's output — re-check both when
 * bumping the shiki / @shikijs/twoslash dep:
 *   - `.twoslash-query-presisted` (used below at the :has() reserve and the query-popup rules)
 *     mirrors an intentional MISSPELLING ("presisted", not "persisted"); if upstream fixes the typo
 *     these rules silently stop matching (no error).
 *   - `.twoslash-hover` backs keyboard access: twoslash_render.mjs stamps tabindex="0" on exactly
 *     `<span class="twoslash-hover"`, and the :focus-within rules below reveal the popup on focus.
 *     If a future Shiki emits an extra class on that span the tabindex no-ops and keyboard focus
 *     silently regresses to hover-only. */
