## MODIFIED Requirements

### Requirement: Enriched board-level card listing
The system SHALL provide a `card list --board <id>` operation that returns all cards across all lists in a board, with each card enriched with the `listName` field and a `labels` field. The operation SHALL: (1) call `GET /boards/{id}` to retrieve the board and its included lists, cards, labels, and cardLabels, (2) build a card-to-label-names map by joining `cardLabels` with `labels`, (3) inject `listName` and `labels` into each card. The `labels` field SHALL be an array of label name strings. The `--limit` flag SHALL apply to the total number of cards returned across all lists.

#### Scenario: List all cards on a board
- **WHEN** `pcli card list --board <id>` is executed
- **THEN** the system SHALL return all cards from all lists in the board
- **AND** each card SHALL include a `listName` field with the name of its containing list
- **AND** each card SHALL include a `labels` field with an array of label names attached to that card

#### Scenario: Card with multiple labels
- **WHEN** a card has two labels ("bug" and "urgent") attached
- **THEN** the `labels` array for that card SHALL contain both "bug" and "urgent"

#### Scenario: Card with no labels
- **WHEN** a card has no labels attached
- **THEN** the `labels` array for that card SHALL be an empty array (not null)

#### Scenario: Board card listing with limit
- **WHEN** `pcli card list --board <id> --limit 10` is executed
- **THEN** the system SHALL return at most 10 cards total across all lists
- **AND** each card SHALL include the `listName` and `labels` fields
