FullStackFusions — token optimization blog series

Projects/fullstackfusions.md lists a goal:

Publishing technical blog series (AWS SAA-C03, Harness Engineering, token optimization)

The vault already has a substantial, structured body of research on exactly this topic in TechResearch/:

• research-rtk and rtk-vs-headroom (RTK_Rust_Token_Killer/)
• research-headroom and headroom-compression-guide (Headroom_Token_Compression/)
• harness-rtk-headroom-synthesis (Harness_Engineering/) — a three-layer synthesis (Harness / RTK / Headroom) that reads as a near-complete blog-post outline already.

This research is ready to be drafted into the "token optimization" entry of the blog series without further primary research — mainly needs an editorial pass using Prompts/how_to_write_blogs/continuous_blog_series_with_curiosity.md as the writing prompt.
