Repeated layouts links on MJML page

Low Severity

This page already links to /integrations/email/layouts at the top. The new dark-mode and button sections add two more markdown links to the same path; only the first mention on a page should be linked.

Risk MEDIUM: Updates email layout, MJML, and client preview documentation with new dark mode branding variables and button styling sections across three content sections.

Reasons

All 5 changed files are .mdx content files only — no components, config, or build files are modified, ruling out HIGH risk.
Changes span three separate documentation sections (content/integrations/email/, content/multi-tenancy/, content/template-editor/), triggering the MEDIUM cross-section rule.
The diff is content-heavy at 158 additions / 23 deletions, adding substantial new documentation sections (button styling, dark mode support in MJML).
No new pages are added and no sidebar navigation files are modified, which keeps the risk from escalating further.
Cursor Bugbot flagged 2 potential issues in a prior review that may warrant attention.

Notes

Verify the new branding variable tables in layouts.mdx, overview.mdx, and branding.mdx are consistent with each other and with the actual API — all three now list 8 branding properties and their defaults should match.
Review the MJML code examples in mjml.mdx for correctness — the CSS in the <mj-style> block appears compressed onto fewer lines which may affect readability.
Confirm the client previews availability change (client-previews.mdx) from Enterprise-only to all paid plans is accurate and approved by product.

This lgtm pending any updates to address Emi's comment. Not sure if the CSS on the button styling example needs to be changed/if we always fall back to those defaults for the dark attributes in the code (i.e. vars.branding.dark_primary_color will always have a value even if it hasn't been explicitly set, meaning that we won't ever evaluate any of the fallbacks on background-color: {{ vars.branding.dark_primary_color | default: vars.branding.primary_color | default: "#000000" }} )

This is only tangential to this PR, but should we ticket adding these properties to the OpenAPI spec so that they're included in settings.branding in the reference here?
