   REM CONVERSION CHEATSHEET (1rem = 16px)
   - 基本式: rem = px / 16
   - ユーティリティ命名例（あなたの方式）:
       0.25rem -> 025 / 1rem -> 100 / 1.25rem -> 125 / 1.5rem -> 150 …等
   -----------------------------------------------------------------------
   |  px  |   rem   | code |  px  |   rem   | code |  px  |   rem   | code |
   |------|---------|------|------|---------|------|------|---------|------|
   |   4  | 0.25rem | 025  |  36  | 2.25rem | 225  |  80  | 5.00rem | 500  |
   |   8  | 0.50rem | 050  |  40  | 2.50rem | 250  |  96  | 6.00rem | 600  |
   |  12  | 0.75rem | 075  |  48  | 3.00rem | 300  | 112  | 7.00rem | 700  |
   |  16  | 1.00rem | 100  |  56  | 3.50rem | 350  | 128  | 8.00rem | 800  |
   |  20  | 1.25rem | 125  |  64  | 4.00rem | 400  |      |         |      |
   |  24  | 1.50rem | 150  |  72  | 4.50rem | 450  |      |         |      |
   |  28  | 1.75rem | 175  |      |         |      |      |         |      |
   |  32  | 2.00rem | 200  |      |         |      |      |         |      |
   -----------------------------------------------------------------------
   よく使う値:
     20px=1.25rem(125), 28px=1.75rem(175), 36px=2.25rem(225), 40px=2.5rem(250),
     48px=3rem(300), 64px=4rem(400)
   補足:
     ・ユーティリティ例: .u-mb-125 { margin-bottom: 1.25rem !important; }
     ・細かい値が必要なときは 062=0.625rem(10px) などを個別に追加
