/** 对话轨迹 — the official 轨迹 (trajectory) rail compressed into one card.
 *
 *  One ROW per lane, exactly the lanes the official timeline draws — 输入 (a user
 *  or steering message), 模型 (an assistant step) and 工具 (a tool call) — in that
 *  order, and all three lanes are always drawn (an empty lane is an empty track,
 *  as in the official strip). Every beat is one bar in its own lane, oldest left,
 *  newest right. The card renders the official HORIZONTAL geometry (the official
 *  `min(width*.08%, 1px)` gap, the 2px floor, 1px corners) but its own VERTICAL
 *  layout: three flush bands filling the card's remaining height.
 *
 *  WIDTH is a per-card switch (`泳道宽度`), mirroring the official toolbar's 时长
 *  toggle:
 *   - 按时长 (default): the recorded-duration projection — a bar's width is its
 *     share of the window's total duration (idle compressed), so a 26.7s tool
 *     call is visibly longer than a 17ms one; anything under the official 2px
 *     floor is drawn at 2px;
 *   - 等宽: the official DEFAULT projection — one equal slot per beat, back to
 *     back, the slot frozen at TRAJECTORY_WINDOW beats so the row stops
 *     re-scaling as the window rolls (n beats share the lane while it fills).
 *
 *  The subtitle is the window's per-lane counts, so the numbers and the lanes
 *  always describe the same 30 beats. */
