Static files cache headers and versioning

[unrealbg]

Problem

Static assets lack long-lived cache headers and versioning, causing suboptimal loading and CDN usage.

Proposal

• Set proper Cache-Control headers for static assets
• Apply asset versioning (hash or version suffix)
• Ensure CDN-compatible config

Alternatives considered

• No versioning, short cache

Acceptance criteria

• Proper Cache-Control headers set
• Asset versioning applied (hash or version suffix)
• CDN-compatible configuration

Technical notes

• Use StaticFileOptions for headers
• Integrate with Tailwind build output

Risks

• Cache busting may fail if config not aligned with build process.
