/**
 * @tag loquix-feedback-form
 * @summary Higher-order feedback flow: thumbs up/down + reason chips + optional comment.
 *
 * Composes two `loquix-action-feedback` buttons into a single flow, then opens a
 * reasons + comment card once a sentiment is picked. The inner `loquix-feedback`
 * events are intercepted (stopPropagation) so consumers only ever see the
 * higher-level `loquix-feedback-submit`.
 *
 * The reason payload carries a stable `FeedbackReason` ID, never the localised
 * chip label.
 *
 * @csspart buttons - The thumbs row.
 * @csspart form - The reasons + comment card shown after a sentiment is picked.
 * @csspart reasons - The radiogroup of reason chips.
 * @csspart chip - A single reason chip.
 * @csspart textarea - The comment textarea.
 * @csspart submit - Submit button.
 * @csspart cancel - Cancel button.
 * @csspart thanks - Thanks message shown after submit.
 *
 * @fires loquix-feedback-submit - When the user clicks Send.
 *   Detail: `{ sentiment, reason?, comment? }`.
 *
 * @cssprop [--loquix-ai-color] - Active chip background and primary button colour.
