Align Press and Media text color with site typography

[addu2612]

Summary

Fixes #128 by aligning the Press & Media page text color with the rest of the website.

Root cause

The introductory body copy on the Press & Media page used a darker gray token than the equivalent marketing pages, which made the page typography inconsistent with the rest of the site.

Changes

• update the Press & Media hero body copy from text-gray-700 to text-gray-600
• keep the rest of the page structure and content unchanged

Validation

This is a tightly scoped style-token update in a single page component. Full local validation was not available in the restricted sandbox environment.

Merge checklist

• I have not included unrelated refactors or unused code
• I have described the root cause and the implemented fix
