IDEA for discussion: keep the composer quiet at rest, make its two pickers discoverable, and preserve what the user meant to send.

• Separate model and reasoning with a single divider. Each has its own hover and click target; the highlights meet at the divider without a gap or permanent boxes.
• Preserve literal paths, URLs, and inline code through paste and display. Multiline paste replaces the selection in place and keeps Windows blank lines. The literal-paste work builds on Julius’s fix(web): pasted URLs and paths keep their underscores #25264.
• Preserve edits made while a send is preparing, including multi-model sends. When an edited queued turn starts, recover its attachments and context chips without overwriting a separate draft.
• Give the collapsed phone web composer the same primary actions as the expanded one, including Stop. Space activates a focused sidebar thread, and desktop typing skips phone-only layout measurements. Native mobile is unchanged.

Important files

• apps/web/src/components/chat/ComposerControlsBar.tsx — model/effort divider and adjoining hit targets.
• apps/web/src/components/ComposerPromptEditorTiptap.tsx — paste and caret behavior.
• apps/web/src/composerDraftStore.ts — stale-send guard and queued-edit recovery.
• apps/web/src/components/chat/ChatComposer.tsx — shared primary actions and mobile-only wrap measurement.

Validation: vp run check:changed passed (377 affected tests, plus compiler checks). Exercised independent picker menus, exact pasted text through a Replay turn, and Stop at a 390px browser width. Measured 0px between the hovered model button and the divider.
