Summary

  • Adds a public tagWeight option to CreateServerHeadOptions that allows users to override the default CAPO tag weight function. This enables reordering <head> tags per-request — e.g. promoting SEO meta above styles when the request comes from a bot.
  • Adds a meta-beyond-1mb validation rule to the ValidatePlugin that warns when meta tags are rendered beyond the crawler byte parsing limit (default 1MB). Social crawlers (Facebook, Twitter) only parse the first ~1MB of HTML, and large inline styles can push OG/SEO meta past this limit.
  • capoTagWeight is already exported from unhead/server, so users can easily wrap it:
import { createHead, capoTagWeight } from 'unhead/server'

createHead({
  tagWeight(tag) {
    if (isBot && tag.tag === 'meta' && tag.props.property?.startsWith('og:'))
      return 55 // just above styles (60)
    return capoTagWeight(tag)
  }
})

Closes #693

Test plan

  • tagWeight option test: custom weight function promotes meta above styles
  • meta-beyond-1mb validation rule: warns when meta rendered past configurable byte limit
  • meta-beyond-1mb does not warn when within limit
  • All 97 existing tests continue to pass
  • Type check passes

… rule

Allow users to customise CAPO tag weights via `CreateServerHeadOptions.tagWeight`.
This enables reordering `<head>` tags based on request context (e.g. promoting SEO
meta above styles for bot requests).

Also adds a `meta-beyond-1mb` validation rule to the validate plugin that warns
when meta tags are rendered beyond the crawler byte parsing limit (default 1MB),
which can happen when large inline styles push OG/SEO tags too far down.
