Acceptance criteria

• Error email translation strings contain complete anchor tags with href placeholder(s) instead of separate opening/closing tag placeholders
• Inline styles (e.g. link color) are injected after translation, not within the translatable string
• HTML and plain text email output remains visually identical to current behavior
• Existing wp_kses allowlist in the HTML template continues to sanitize anchor tags correctly

Implementation Brief

Backend

• Update file includes/Core/Email_Reporting/Content_Map.php

  • Refactor the four error email body strings to use inline <a href="%s"> within the translation string instead of separate opening/closing tag placeholders:
    • error-email-permissions-search-console: change to single %s href placeholder
    • error-email-permissions-analytics-4: change to single %s href placeholder
    • error-email-report-search-console: change to two %s href placeholders (settings link + help link)
    • error-email-report-analytics-4: change to two %s href placeholders (settings link + help link)
  • Update translator comments to reflect the new placeholder format (e.g. /* translators: %s: "get help" link URL */)
  • Add a new static method add_inline_link_styles( string $html ) that post-processes translated body paragraphs to inject inline styles onto anchor tags:
    • Match <a tags and add class="link" and style="color:#108080;" attributes
    • This replaces the current pattern of baking styles into the get_body_args return values
  • Refactor get_body_args() to return only the URL strings (not full <a> opening/closing tags):
    • error-email-permissions-*: return array( $help_url )
    • error-email-report-*: return array( $settings_url, $help_url )
  • Apply add_inline_link_styles() in get_body_with_args() to each paragraph after vsprintf substitution

• Update file includes/Core/Email_Reporting/Batch_Error_Notifier.php

  • Verify no changes needed — this file calls Content_Map::get_body_args() and Content_Map::get_body_with_args() which will handle the new format transparently

• Update file includes/Core/Email_Reporting/templates/simple-email/parts/content.php

  • Verify the existing wp_kses allowlist for anchor tags already permits href, style, and class attributes — add class to the allowlist if missing

Test Coverage

• Update file tests/phpunit/integration/Core/Email_Reporting/Content_MapTest.php
  • Update test_get_body_with_args_substitutes_placeholders and error-email-related assertions to match new string format (inline anchors instead of separate open/close tags)
  • Add test for add_inline_link_styles method: verify styles are injected on anchor tags
  • Add test that error email body paragraphs after get_body_with_args contain complete <a href="..."> tags with inline styles
  • Add test that Plain_Text_Formatter::convert_links_to_text correctly extracts URLs from the new format
