#7 在改到期天数时连带删掉了 #4 的 `Num` 槽位：摘要行、表格网速列、展开详情的网速行重新按最宽形态预留宽度，数字变化时两侧不再跳动。到期天数仍由 `expiresIn` 给出。

+ * A figure that changes on every push, held in a slot wide enough for the widest
+ * form it can take, so a node moving from 19K/s to 8.19K/s leaves the rest of the
+ * line where it was. Right-aligned, so the unit keeps its place and the digits
+ * grow towards the arrow instead.
+ *
+ * `ch` is the width of a digit under the tabular figures this selects, so a slot
+ * follows whatever size it is drawn at, down to the 10px the table uses on a
+ * phone. The width travels as a custom property rather than `min-width` itself,
+ * which is what allows a caller to drop the reservation where the column is too
+ * narrow to hold it: an inline style would outrank the class that does so.
