Summary

The pull request updates the documentation style guide with the following changes: for 'framing-apollo-products', it suggests using simpler terms like 'move' or 'adopt' instead of 'migration'; in 'framing', 'Apollo' replaces 'We' for clarity; for 'structural-elements', admonitions are now required for end-of-life warnings; 'text-formatting' now mandates descriptive noun phrases for link text; 'verb-tense-and-voice' requires active voice for Apollo Server 4 status; the 'voice' section encourages a more authoritative tone; and 'word-and-symbol-usage' restricts the use of 'since' to time-based contexts only.

[warning] 11-11: docs/source/index.mdx#L11
Framing Apollo Products: Use simpler language like 'move' or 'adopt' instead of 'upgrade' or 'migration' where possible.

Framing: Use 'Apollo' instead of 'We' to clearly identify the entity making the recommendation.

Structural Elements: Use a admonition for highly important information like end-of-life warnings instead of a blockquote.

Text Formatting: Avoid using vague phrases like 'previous versions' as link text; use a rich noun phrase instead.

Verb Tense and Voice: Use active voice to describe the status of Apollo Server 4.

Voice: Use a more authoritative and encouraging tone rather than just recommending.

Word and Symbol Usage: Avoid using 'since' as a synonym for 'because'.

> We recommend that all users of [previous versions](./previous-versions) of Apollo Server move to Apollo Server 5 as soon as possible. Apollo Server 4 has been end-of-life since January 26, 2026. Refer to the [adoption guide for v4](/apollo-server/migration/) or [v3](/apollo-server/migration-from-v3/).

@mabuyo I just want to confirm that you think this paragraph still makes sense as written

[mabuyo]

Yes I think it still stands! We are going to discuss possibly splitting off v4 and v5 though to further reduce confusion on v4 being EOL.
