What's Changed

add: bundled item images resolved from install-dir-relative override paths

• Items that no wiki or community CDN has a picture for now show a real image instead of the
  category-icon placeholder: all 95 required items are covered, and 65 of the 69 rewards
  without an API image (the 4 that remain are listed in docs/reward-images.md).
• 27 hand-made screenshots and crops ship with the app — visible both as the 46×46 thumb and in
  the full-window preview overlay, which means practically every inventory row is now clickable.
• The image override files accept a new, simpler value: a path relative to the install dir. You no
  longer need a hosted URL or a machine-specific absolute path to add your own picture.
• Personal images still belong in %AppData% — the bundled folder is replaced on every update.
  src/Resources/img/README.md is the step-by-step for adding one.
• The "Where to Find" navigation item gets a location icon instead of the book/question-mark glyph.
