Wrapper tab ---------------------------------------------------------- The docs sections render in the left sidebar as `anchors`, which Mintlify only allows nested inside a tab. That wrapper tab ("AppSignal Documentation", linking to /getting-started) is structurally required but visually redundant — the sidebar already lists every section — so we take it out of view. We use a visually-hidden (sr-only) pattern rather than `display: none` on purpose: it keeps the descriptive link in the rendered DOM and the accessibility tree, so its anchor text stays meaningful to crawlers/screen readers instead of being dropped (the SEO intent). /getting-started is also linked from in-content pages and the sidebar anchor, so nothing is orphaned. NOTE: this selector is coupled to Mintlify's navbar markup (a tab `

` inside #navbar whose link href ends with /getting-started). We match the END of the href, not the start, so the tab is hidden on every locale: the English tab links to /getting-started and each translated locale links to //getting-started (/nl/…, /pt-BR/…, /fr/…, /de/…). A start-anchored match only caught English, leaving the tab visible and overlapping the language selector on the translated pages. Re-check it on Mintlify version bumps.
