v0.0.340

Added

• A README front page: hero, pitch, badges, nav, then the spec sample and what the
  product looks like. The content was already strong; what it lacked was the visual
  first impression. The graphics are authored in this repository - no icon package, no
  external asset host, no hand-copied path data:
  .github/assets/hero-{light,dark}.svg, one per theme and served through a
  <picture>, drawing the sentence the README opens with rather than decorating it -
  one spec, one runner, the surfaces that reach it and the four refusals underneath,
  in the app's own palette read out of globals.css and converted rather than
  eyeballed; and docs/assets/mark.svg, the same mark alone, which is now the docs
  site's logo and favicon, which the site did not have. One file, not two: an earlier
  draft had a copy in .github/assets/, which is the second-source defect this
  repository keeps citing. (#783)
• Release and stars badges - the two the header lacked - plus a star-history image
  before the footer. Image paths are relative, so they render in a pull request as
  well as on main; absolute raw.githubusercontent URLs would show broken images to
  whoever reviews a change about graphics. (#783)
• Three screenshots - the builder, the catalog, the chat surface - at 1600px,
  palette-reduced to 220 colours, 392KB for all three. Taken from a make dev run
  against a throwaway database rather than a developer's own, which held eleven E2E
  fixtures and four scratch agents; the fresh one was dropped afterwards and the
  developer's eleven agents verified still there. No shot shows a live model answer,
  deliberately: the alternatives were to spend somebody's tokens or to fake a
  transcript, so the chat shot is the composer with a real question typed and the agent
  picker showing which agent will answer. (#783)

Fixed

• The docs table promised "Spec, version, exposure, run - the four nouns" where
  concepts.md has five: the trigger was added and one of the two pages updated.
