## [Unreleased]

### Added

- **Visual editors for loot, trade, and recipe content**: New drag-and-drop
  visual editors for loot tables (`LootPoolVisualEditor`, `LootEntryEditor`,
  `LootItemDropZone`, `DiceRollEditor`), trade tables (`TradeTableVisualEditor`,
  `TradeTierVisualEditor`, `TradeEditor`), and crafting recipes
  (`RecipeEditor`, `ShapedRecipeEditor`, `ShapelessRecipeEditor`,
  `CraftingSlot`) replace raw JSON editing for these formats.
- **Block & item picker dialogs**: New `BlockPickerDialog` and
  `ItemSpritePicker` browse vanilla blocks and items by sprite. Backed by
  pre-rendered atlases (`block-sprites.png`, `item-sprites.png`) generated by
  the new `generate-block-atlas.mjs` and `generate-item-catalog.mjs` build
  scripts.
- **Simplified Spawn Rules editor**: New `SimplifiedSpawnRulesEditor` (with a
  `SpawnRulesEditorWrapper` that toggles between simplified and advanced views)
  makes spawn-rule authoring approachable without learning the full schema.
- **Slash-command palette for in-app actions**: New tool commands —
  `Add`, `Deploy`, `Export`, `FormatDocument`, `Info`, `OpenFile`,
  `OpenSettings`, `ReloadProject`, `SwitchMode`, `ToggleInspector`,
  `Validate` — accessible from the command bar.
- **Global error overlay**: New `GlobalErrorBoundary` and
  `GlobalErrorOverlay` (backed by `core/ErrorService`) catch uncaught
  exceptions and present a friendly recovery surface instead of a blank
  screen.
- **Pseudo-locale**: Added `pseudo.json` locale and `generate-pseudo-locale.mjs`
  for visual i18n testing (long strings, accented characters), plus a new
  `withLocalization` HOC and Playwright pseudo-locale specs.
- **New block traits**: `ExplosionResistantBlockTrait`, `FenceBlockTrait`,
  `FlammableBlockTrait`, `RedstoneProducerBlockTrait`, `SlipperyBlockTrait`
  (replacing the removed `ContainerBlockTrait`) for richer
  `mct validate` reporting.
- **Custom dimension validation**: New
  `CustomDimensionWorldDataInfoGenerator` plus
  `CustomDimensionValidationTest` validate world content that uses custom
  dimensions.
- **Trading behavior model**: New `ITradingBehavior` interface and content
  schema (`trade_table.json`) round out first-class support for villager
  trade tables alongside the new visual editor.
- **Pack header forms**: New `behavior_pack_header_json.form.json` and
  `resource_pack_header_json.form.json` provide guided editing for pack
  manifest headers.

### Changed

- **Translations refreshed**: All shipped locales (28 files: bg_BG, cs_CZ,
  da_DK, de_DE, el_GR, en_US, es_ES, es_MX, fi_FI, fr_CA, fr_FR, hu_HU,
  id_ID, it_IT, ja_JP, ko_KR, nb_NO, nl_NL, pl_PL, pt_BR, pt_PT, ru_RU,
  sk_SK, sv_SE, tr_TR, uk_UA, zh_CN, zh_TW) updated to cover the new
  editors, dialogs, and command palette strings.
- **Schema-driven editors expanded**: Updates to `SchemaForm`,
  `SchemaParser`, `SchemaEditor`, the new `DataFormComponentAccordion`, and
  the `MaterialRenderer` improve consistency between simplified and advanced
  editing modes across biome, entity, block, item, feature, and event
  editors.
- **CLI hardening and JSON contract**: Stable `schemaVersion: "1.0.0"` JSON
  output across `version`, `info`, `validate`, `eula`, `passcodes`,
  `set-server-props`, `world`, `aggregate-reports`, `search`, `setup`, and
  `set` commands. New CLI tests cover JSON contracts, exit codes, the
  `--yes` flag, and bad-path handling.
- **Inspector view**: PASSED rule rows are now hidden by default. Errors,
  warnings, and recommendations remain visible. To show passed rows again,
  toggle the "Passed" filter chip at the top of the Inspector panel.
- **Format on save**: now OFF by default. Hand-formatted JSON (compact arrays,
  inline component groups, comments) is preserved on save. To re-enable
  auto-format on every save, open the Settings panel and turn on
  "Format JSON and script on save".
