P0: Upgrading to Next.js 15 without also upgrading `nextra` and `nextra-theme-docs` from v2 to at least v3 (or v4) will almost certainly break the build. Nextra 2.x was designed for Next.js 13/14; the Nextra project itself couples Next.js 15 support with Nextra 3+. Either hold `next` at v14, or upgrade `nextra`/`nextra-theme-docs` alongside this change.</violation>
