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/…, /zh-CN/…). 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. Scoped to #navbar so the sidebar anchor and other /getting-started links are untouched. */ #navbar li:has(> a[href$="/getting-started"]) { position: absolute !important; width: 1px !important; height: 1px !important; padding: 0 !important; margin: -1px !important; overflow: hidden !important; clip: rect(0 0 0 0) !important; clip-path: inset(50%) !important; white-space: nowrap !important; border: 0 !important; } /* =========================================================================== AppSignal branding. Ported from PR #494 (https://github.com/appsignal/appsignal-web/pull/494), with every selector re-verified against the current Mintlify/Luma DOM (the nav was rebuilt since #494, so several selectors were updated). These rules apply in BOTH themes: the structure/typography is theme-agnostic and every color is a token (see "Design tokens" above) that resolves to the light value under `:root` and the dark value under `.dark`. Dark mode is enabled via docs.json `appearance.default: "system"`. The few selectors that target Mintlify's light utility classes (e.g. `bg-background-light`) still match in dark because Tailwind keeps both light and `dark:` class names in the attribute — only the token value swaps.
