Redraw hero.png with proper alpha channel and move stage names to caption - #13

The committed hero.png keyed badly. It carried an opaque cream background remnant sitting above the forge and 250 separate speckle regions of keying debris — 258 regions in total against 4 objects, with subject pixels bleeding onto the canvas border. Invisible on white, obvious on any mid-tone. It was also stale and unfixable in place: `forge anvil temper quench` was painted into the pixels, so it still read as a four-stage pipeline after `hone` became stage five, and painted text cannot be re-cropped, restyled or read at favicon size. Redrawn with the transparent-logo skill as five objects and no lettering — coke forge, anvil, tempered blade, quenching tub, whetstone — and cut to a real alpha channel. The stage names now live in a README caption beside the pipeline table, where they can be edited. Cut: 5 regions for 5 objects, 2.06% partial alpha, zero opaque key-coloured pixels, zero border bleed, no fringe over white, mid-grey or #0d1117. Four plates were rejected first, each for a property of the subject rather than of the keyer: an open recess bleeding the key through its hatching, glowing flame wisps taking the key colour and detaching, a "sword blade" arriving without a hilt, and a narrow enclosed gap under a bridging clamp surviving the keyer's hole test because a sliver is mostly antialiased fringe. All four are recorded in docs/assets/README.md with the fix each one bought.

Summary
Regenerate the pipeline hero image (
docs/assets/hero.png) with a clean alpha channel and remove embedded text. The new image is generated from a detailed subject prompt and uses proper keying to eliminate background artifacts. Stage names are now documented in the README caption instead of painted into the image pixels.Changes
docs/assets/hero.png: Replaced with a new 5-object plate (forge, anvil, tempered blade, quenching tub, whetstone) featuring:
transparent-logoskill withgemini-3-pro-imagedocs/assets/hero-subject.txt (new): Committed the exact subject prompt used to generate the plate. Documents the precise specifications that produced the clean result (e.g., "coals glowing in orange, amber and straw yellow only … no flame, no wisp and no spark").
docs/assets/README.md (new): Provenance documentation explaining:
README.md: Updated the hero image alt text to name all five stages and added a caption below the image reading the stage names left to right.
CHANGELOG.md: Documented the change under
Changedsection.Implementation notes
The previous hero image carried an opaque cream background above the forge and ~250 speckle regions of keying debris, plus painted text that showed only four stages long after
honebecame stage five. The new plate is generated deterministically from a subject prompt (recorded inhero-subject.txt) and cut with proper alpha keying. The generation command and cut parameters are documented indocs/assets/README.mdfor reproducibility of the process, though each run produces a different image (image models are non-deterministic).https://claude.ai/code/session_018ND32T9ygT3PJ6A9EjGV23
