## Summary On kanban cards, the title was being truncated even when the checkbox wasn't displayed. The checkbox is hidden via `opacity: 0` on the card's non-hovered state, which keeps it in flex flow and still reserves its ~24px of width — so the title's flex item was shrinking unnecessarily. This change collapses the checkbox container's `max-width` to `0` (with `overflow: hidden`) while it's hidden, and expands it back to the checkbox's natural size (`spacing[6]` = 24px) on hover or when selected. The existing `transition: all ease-in-out 160ms` animates the title expanding into the freed space. ### Before Title truncates with ellipsis even though the checkbox slot is empty: <img width="350" alt="before" src="https://i.imgur.com/placeholder-before.png" /> ### After Title uses the full row width when not hovered; the checkbox slides in on hover (or when the card is selected) and the title reflows. ### Tooltip The full title is already exposed on hover when truncated — `RecordChip` → `Chip` already wraps the label in `OverflowingTextWithTooltip`, which detects overflow (`scrollWidth > clientWidth`) and renders an `AppTooltip` with the full text. No additional wiring needed. ## Test plan - [ ] On a kanban board, verify a long record title now uses the full card width when the card is not hovered (no ellipsis if the title fits). - [ ] Hover the card: the checkbox slides in smoothly (animated), and the title reflows (may now truncate if it doesn't fit). - [ ] Hover the (now-truncated) title: tooltip with the full title appears. - [ ] Select the card via the checkbox: checkbox stays visible (and title stays in its hover-state width) without hovering. - [ ] Compact view (eye icon) still renders correctly. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 4.7 <noreply@anthropic.com>
