📄 Description

Adds a TH04 case study showing how its original 16-bit PC-98 DOS code spaces a bullet ring and aims it at the player. Fresh REA instructions are paired with a five-step C++ comparison and a ring diagram; homepage and showcase-index entries link to the new page and the requested reconstruction repository.

The page credits TH04's maintained source and recorded compiler checks separately from the new REA inspection. Public provenance pins the target, source checkpoint and evidence. No original game assets, executables, private paths or raw result bundles are included. Pages remains manually dispatched.

Validation:

Website verifier: 12 HTML pages, 185 local references, SVG XML and downloadable ZIP.
Browser: root and /rea/, 32 copy checks, five comparison steps, eight viewport widths, keyboard, reduced motion and no-JavaScript content.
Fresh real Ghidra verification through published REA 4.1.0: DOS load image verified, all 84 checks match; shown instructions match the function dossier. No Hopper verification was needed or run.
Independent claims/privacy reviews passed; seven immutable public source links match the local TH04 checkpoint.
npm run check:fast.

The two clean compiler replays and 2,139 matching bytes are recorded TH04 checks, reviewed against their retained receipt and source hashes; the website update does not rerun the compiler or game.
