/* 第二年 — one stylesheet, served from the binary.

   A rate card under the counter glass: cold ink-blue ground, and the numbers
   in the two colours a ledger has ever needed — one for the side you are on
   and one for the side you are not. The accent is a brass-teal, because this
   page is about a choice rather than a warning, and nothing on it is an alarm.

   The tones are `clear`, `fine`, `knife`. They say how far the rate would have
   to move before the answer flips. None of them is advice. */
