* Accessibility: ARIA labels and toggle states
Screen readers couldn't name several icon-only controls or tell whether the
tool toggles were on. This adds accessible names and exposes toggle state,
with no behavior or layout change.
- Icon-only buttons get aria-label: web/shell tool toggles, the "more tools"
overflow button (+ aria-haspopup), and the color-reset buttons.
- Unlabeled inputs/selects get aria-label: memory + skills search, model-picker
search, memory sort, theme font/density selects, and the new-memory / skill
(title, when-to-use, how, tags) fields, which only had a visual floating label.
- Toggle state via aria-pressed, kept in sync at the existing .active write
sites: web/shell toggles (setupToggle) and the Agent/Chat mode buttons
(initModeToggle). Static aria-pressed added in the markup so the attribute
exists before JS runs.
Scope: first slice of the ROADMAP accessibility pass. Focus-visible/contrast,
reduced-motion, and modal dialog roles/focus-trap are left for follow-ups.
Checks: node --check static/app.js. No Python touched.
* Accessibility: mark chat log busy while streaming
The chat log is an aria-live="polite" region, so streaming a response
token-by-token made screen readers announce every partial update — noisy and
unreadable. Set aria-busy="true" on #chat-history while a response streams and
back to "false" in the stream's finally block. Assistive tech then waits for
the settled message and announces it once.
Checks: node --check static/js/chat.js.
In Compare each pane renders into a sandboxed <iframe>. A file dropped on
a pane was handled by the iframe (browser default), so the browser loaded
the file *inside* the pane — appearing 'behind' the app — instead of
attaching it. The existing #chat-container drop handler never sees the
event because drag events don't bubble out of an iframe.
While a file drag is active in Compare, raise a single full-window drop
shield above the panes/iframes so the drop lands on the parent document,
then route the files into the shared composer (the same pending-files
pipeline the file picker and paste already use). Scoped to Compare via the
.compare-active class, so normal chat and the tool dropzones (gallery, RAG,
document editor, …) are unaffected.
Verified with a headless-Chromium integration test: synthetic file
dragover raises the shield, drop attaches the file to the composer, and
non-Compare mode is unaffected. Also ran node --check static/app.js.
Follow-up to #271. Skip svgifyEmoji when body.text-emojis is set so
deEmojify can strip Unicode from replies; also unwrap existing .emoji
spans from messages rendered before the setting was applied.
