feat(words): insertImage operation + command + CSS + extension stub (F3.6, F3.9, F3.10)
F3.6 — insertImage reducer + command:
- engine/operations.ts: insertImage(state, options) — atomic insert
(URL required, optional alt/caption/width/height/align/status).
Replaces an empty paragraph cursor lands on, otherwise inserts after.
Caret lands on the new paragraph following the image (image is
atomic — no caret inside the figure).
- engine/commands.ts: 'insertImage' case added to WordsCommand union +
applyWordsCommand switch. Public command surface: provider can call
applyWordsCommand(state, { type: 'insertImage', src, alt?, ... }).
F3.9 — eidos CSS for image block:
- figure[data-words-block='image']: centered flex column with border,
bg, padding, gap.
- img: max-inline-size 100%, auto height, user-select none.
- figcaption: italic, centered, status-color, smaller font.
- data-words-image-align='left'/'right': flex alignment + auto margins.
- data-words-image-status='pending': opacity + grayscale + "Uploading…"
::after pseudo-text.
- data-words-image-status='error': threat border + "Upload failed"
::after pseudo-text.
- :focus / :focus-within: 2px accent outline so the atomic block has
a visible selection state.
F3.10 — imageExtension stub:
- extensions/image/image-extension.ts: WordsExtension shape with
name='image', nodeTypes=['image'], factories.image=createImage,
commandNames.insertImage='insertImage'. Hooks intentionally absent
(engine still hardcodes branches today; stub publishes the public
shape parallel to tableExtension).
- extensions/index.ts exports imageExtension alongside tableExtension.
Morfo:
- data-block + data-words-node value sets include 'image'.
- New optional attrs declared: data-words-image-align (left/center/
right), data-words-image-status (pending/error). Now the eidos CSS
selectors validate against the morfo contract.
211/211 tests pass in words soma + morfo scope.
