Minor doc fixes across the corpus (ten review findings)

- 10 cites 11 for Add Attachment and the lane-width menu items
- 04 uses ⌘/⇧ symbols for click modifiers; card moves scoped to the
  ⌥⌘ chord; ../WISHLIST.md path fixed
- 03 says stepper (plus the menu pair) in the editing-surfaces table
- 06 says one commit per debounce window
- 03/10 Reduce Motion lists aligned at five items; rubber-band
  disambiguated as the lane-resize feedback
- 11 requires the trash shown for Empty Trash
- 02 rewords and-peers

 - **Cards**: clipboard. ⌘X the selection, move selection to the destination (arrows), ⌘V — between lanes, within a lane (paste lands after the anchor card), and across boards (04-interactions.md's staged clipboard). This is the committed drag-free move story; it needs no VoiceOver-specific machinery because selection and paste targeting are already keyboard-native.
 - **Lanes**: the defect this doc originally named (lanes had no keyboard-move path) is closed by the keyboard map — with a lane selected, ⌘←/⌘→ move it (Board ▸ Move Left / Move Right, 04-interactions.md); cards gain ⌥⌘↑/⌥⌘↓ within-lane sorting, and cross lanes drag-free via cut/paste (04-interactions.md's clipboard rules). Lanes carry the clipboard too (resettled, 04-interactions.md ▸ Clipboard), so cross-board lane copy/move — once drag-only, the contract's last gap — is ⌘C/⌘X, then ⌘V with the destination board frontmost.
-- **Lane resize**: the header context menu's width stepper (03-board-ui.md) — and its keyboard face, the Increase/Decrease Lane Width menu items (⌥⌘→/⌥⌘←, 04-interactions.md) — is the accessible path; edge drag is enhancement only.

 - **Attachments**: the card window's sidebar items expose Open / Reveal in Finder / Remove via context menu, and the section is keyboard-navigable outright (arrows, Space-QuickLook, Return, ⌫ — 05-card-window.md); adding files drag-free is File ▸ Add Attachment… (⇧⌘A, 11-command-nexus.md) alongside Finder-drop.

 - **Full relative scaling** (decided): relative text styles everywhere, no fixed point sizes. Card face, lane header, and masonry metrics derive from font metrics, so layout survives the largest system text sizes; the no-horizontal-scroll invariant is untouched (lane count is the user's choice; lanes scroll vertically), and 03-board-ui.md's graceful-truncation rules apply at every scale.
 - **Contrast is pinned to WCAG AA.** Lane and card colors render as edge accents (03-board-ui.md's top-edge band / left-edge stripe), so text never sits on them — they are supplementary decoration, never the sole carrier of information, and carry no text-contrast obligation. The ≥ 4.5:1 automatic-contrast rule binds where text does sit on a user-chosen color: the **board** background (palette pairs verified at design time; arbitrary hex computes its text color at runtime against that threshold). An `#RRGGBBAA` background with alpha computes against the color **composited over its effective backdrop** in the active appearance (the board's over the window background; light and dark resolve differently), recomputed on appearance change. Increase Contrast strengthens borders and the selection indicator.
 - **State is never color-alone**: selection is a ring plus trait, cut-pending is dim plus stated value, the trash header is hatched plus labeled — all already patterned; kept as a rule.
-- **Reduce Motion**: reflow-on-drag, search animate-out, the drag replica, rubber-band feedback, and trash animations all get reduced variants (crossfade or instant). **Reduce Transparency**: glass underlays (carousel page dots) go solid.

 - **Full Keyboard Access** (independent of VoiceOver): the board is one tab stop with arrow-key navigation within; every control — lane buttons, popover, card window, welcome — is Tab-reachable.
