## What kind of change does this PR introduce?
Accessibility / lint hardening (Safari keyboard focus).
## What is the current behavior?
`supabase/require-explicit-tabindex` is `'warn'`. Studio’s ratchet was
at 0 but the rule was still ratcheted; www / docs / design-system still
had raw `<button>` / `role="button"` call sites without an explicit
`tabIndex`.
[DEPR-627](https://linear.app/supabase/issue/DEPR-627) · follow-up to
#47984 / #48040
## What is the new behavior?
- Shared config: `'supabase/require-explicit-tabindex': 'error'`
- Swept www / docs / design-system (+ Studio test fixtures the ratchet
skipped)
- Removed the rule from the Studio ratchet + baselines
## To test
Prefer **Safari**. This PR only adds explicit `tabIndex` to raw
`<button>` / `role="button"` call sites — not links, and not controls
that already go through `Button` from `ui`.
### Marketing (`www`) ([staging
link](https://zone-www-dot-com-git-danny-depr-627-promote-req-7ae43c-supabase.vercel.app/))
- [x] Homepage frameworks / dashboard feature tabs — Tab through each
tab button
- [x] Product pages (e.g. `/auth`, `/database`) — section tab switchers
- [x] Narrow viewport — open the hamburger; Tab through menu buttons
- [x] `/partners/catalog` — filter / view controls
- [x] Blog view toggle (list ↔ grid)
### Docs ([staging
link](https://docs-git-danny-depr-627-promote-require-explici-25e46d-supabase.vercel.app/))
- [x] **Desktop (≥ lg):** top-right **⋯ menu** (hamburger icon) — opens
a dropdown that includes Theme. Not a separate theme button.
- [x] **Mobile (< lg):** top-right **hamburger** opens the sheet; close
(X) is the raw button we tagged. Theme inside the sheet uses
`ThemeToggle` / `DropdownMenuTrigger` from `ui` (already supposed to set
`tabIndex`).
- [x] **Code blocks** — copy / language controls
- [x] **Is this helpful?** — X / check are `Button` from `ui` (should
already Tab). After voting **while signed in**, the follow-up “What went
well?” / “How can we improve?” text button is the raw one we tagged.
- [x] **AI Tools → Copy as Markdown** (right rail on a guide) — this is
the only GuidesSidebar control this PR changed. “On this page” TOC items
are **links**, not covered by this lint.
- [x] **Reference docs** (e.g. JS client reference) — section headers
that expand/collapse in the left nav (`Collapsible.Trigger`)
- [x] **Troubleshooting index** — type in the search field, then Tab to
the **clear (X)** control
### Dashboard (`studio`)
No production UI changes in this PR (tests + lint config only). Quick
Safari smoke that prior tabindex work still holds:
- [x] Project sidebar — Tab through primary nav links
- [x] Settings → General — Tab through inputs / buttons
- [x] Storage → Files — Tab a bucket row / file actions
## What kind of change does this PR introduce?
Bug fix: custom icons now respect their source SVG’s stroke/fill and
stroke-width instead of always getting a global stroke.
## What is the current behavior?
Every custom icon gets `stroke="currentColor"` and `strokeWidth={2}`
from `createSupabaseIcon`, so fill-only logos get an extra stroke and
icons designed at `stroke-width="1"` (e.g. postgres, auth) render too
thick. Call sites and the design-system grid needed workarounds
(`strokeWidth={0}`, `FILL_ONLY_ICONS`, `STROKE_WIDTH_FROM_SOURCE`).
## What is the new behavior?
The icon build reads root SVG attributes (`fill`, `stroke`,
`stroke-width`, etc.) and passes them as per-icon defaults. Fill-only
icons (chatgpt, claude, axiom, last9) have `stroke="none"` in source and
render with no stroke; stroke icons keep their source stroke-width (e.g.
postgres at 1). No `strokeWidth={0}` or allowlists needed at call sites
or in the icon grid.

## Additional context
- Added `stroke="none"` to the four fill-only source SVGs;
sentry/grafana/otlp/datadog already had `stroke-width="0"`.
- `createSupabaseIcon` only applies `color`/`strokeWidth` when the
consumer passes them, so `svgDefaults` from the build are used
otherwise.
- Removed workarounds from `icons.tsx` and GuidesSidebar; updated
icons.mdx (defaults + fill-only guidance).
