Standardize frontmatter metadata across documentation files

[BekahHW]

Description

Many documentation files have inconsistent or repetitive keywords in their frontmatter metadata. This makes navigation and discoverability less effective.

Problems Identified

• Repetitive keywords that don't add value
• Inconsistent keyword formatting
• Some files have excessive keyword lists while others have too few
• Keywords don't always match the actual content

Tasks

• Audit all markdown files in the docs/ directory for frontmatter metadata
• Create a standardized set of keywords for different content types
• Remove redundant/repetitive keywords
• Add missing relevant keywords where appropriate
• Ensure consistent formatting across all files
• Document the keyword standards for future contributors

Example Files to Fix

• Coffee table group guides have very long, repetitive keyword lists
• Monthly challenge files have inconsistent metadata
• Procedure files could use more specific keywords

Acceptance Criteria

• All documentation files have clean, relevant keywords
• Keywords follow a consistent pattern
• Documentation for keyword standards is created
• Site navigation and search work effectively
