What

Press / anywhere on the canvas and a small bar opens. Type one plain sentence, press Enter, and it becomes a step:

• titled from the sentence (first letter capitalized; past 48 chars it truncates with … and keeps the full text as the description),
• placed in free space (one column right of the selected step — 286px, the example graph's rhythm — or at the viewport center when nothing is selected, bumping down in 96px rows until the spot is free),
• wired after the selected step (source-right → target-left),
• selected, so the next Enter chains off it.

sentence ⏎ sentence ⏎ sentence ⏎ sketches a whole workflow without touching the mouse. Esc closes, Shift+Enter inserts a newline, and the bar stays out of the way of toasts. The gesture follows the existing shortcut conventions (ignored while typing in inputs, registered in the same onKey handler as ⌘N/⌘D/etc.).

Design choices

• One store action, one undo step. quickAddStep(text, fallback) commits the node and its wire in a single commit, so one ⌘Z removes both — no half-added state.
• The store stays presentation-free: the caller passes the fallback position (App computes the viewport center via screenToFlowPosition), so the action is fully unit-testable.
• The idea is borrowed from how "get-shit-done"-style workflow tools accept a messy sentence and structure it for you, instead of asking the human to fill a form first. Humans brain-dump; the canvas does the tidying.

Tests

• Wired path: title casing, column placement, edge created, selection moved, exactly one history entry, undo removes node+edge together.
• Unwired path: fallback placement, collision bump on the second add, long-sentence truncation + description carry, no edges created.
• Blank input is a no-op (no history entry).

npm run build     # clean

Note: the two storage-failure tests in store.test.ts fail on main before this branch — that's #3, independent of this change.
