making it decorative and preventing duplicate English labeling alongside the
localized heading.
- Around line 72-103: Update the RC download links in the landing page to use
the published universal asset cmux-macos.dmg, and remove the
architecture-specific download links because no RC workflow produces those
filenames. Keep the primary download button functional and remove only the
obsolete architecture-specific UI.
In `@web/messages/es.json`:
- Line 135: Translate the copied English Release Candidate terminology in the RC
namespace, including footer.rc, using locale-specific wording. Update

Mark the logo as decorative.
alt="cmux RC icon" adds a literal English accessible label on every locale and repeats the adjacent h1 identity. Set alt="" so assistive technology uses the localized heading instead of announcing duplicate content.
Proposed fix
- alt="cmux RC icon"
+ alt=""📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
Suggested change
| alt="cmux RC icon" | |

Align the RC links with the published release assets.
The RC page requests cmux-rc-macos.dmg, cmux-rc-macos-arm64.dmg, and cmux-rc-macos-x86_64.dmg. The repository’s release workflow and scripts/build-sign-upload.sh publish only cmux-macos.dmg; no RC pipeline publishes the cmux-rc-* assets. These links can therefore be unavailable after an RC release.
If the RC uses the existing universal DMG, link to cmux-macos.dmg and remove the architecture-specific links. Otherwise, add an RC pipeline that publishes the exact three filenames before exposing these links.

In Next.js, the request lifecycle follows a strictly defined execution order, which determines how headers, rewrites, and Middleware/Proxy interact [1][2][3]. ### Execution Order When a request is received, Next.js processes it in the following sequence [1][2][3]: 1. headers from next.config.js 2. redirects from next.config.js 3. Middleware (or proxy.ts in Next.js 16+) 4. beforeFiles (rewrites) from next.config.js 5. Filesystem routes (public/, _next/static/, pages/, app/, etc.) 6. afterFiles (rewrites) from next.config.js 7. Dynamic Routes (e.g., /blog/[slug]) 8. fallback (rewrites) from next.config.js ### Key Considerations * Middleware/Proxy Execution: Middleware (or proxy.ts in newer versions) runs after headers and redirects defined in next.config.js, but before filesystem routes and beforeFiles rewrites [1][2][3]. * Header Matching: The has and missing fields in next.config.js for headers and rewrites allow you to target specific paths based on the presence or absence of headers, cookies, or query parameters [4][5]. * Middleware Header Modification: You can modify request headers within your Middleware/Proxy using the NextResponse.next({ request: { headers } }) API [1][2][3][6]. These headers are then available to upstream components (like Server Components via the headers() function) [1][3]. * Behavioral Nuances: Be aware that request headers set in Middleware may be merged with response headers in certain rendering contexts, which can sometimes lead to unexpected behavior when accessing headers() in React Server Components [7]. Additionally, in Next.js 16+, middleware.ts is replaced by proxy.ts for routing middleware functionality [8].

Cache the canonical English /rc route.
Next.js 16.3.4 applies headers() rules before proxy.ts. The bare /rc request does not match /${localePrefix}/rc, so it misses publicMarketingCacheHeaders.

locale-prefixed route in the publicMarketingCacheHeaders configuration so
canonical English requests receive the same cache headers.
