加个深色模式背景？

[DellZHackintosh]

深色下只有纯色实在太单调，我让必应根据浅色模式的背景生成了相应的深色模式渐变背景：

平衡：
linear-gradient(90deg,#070c13,7.60286%,#080d16 15.2057%,20.7513%,#090e18 26.297%,27.6386%,#090e18 28.9803%,38.2826%,#0a0f1c 47.585%,48.1216%,#0b1020 48.6583%,53.1306%,#0c1122 57.6029%,61.5385%,#0d1224 65.4741%,68.7835%,#10152a 72.093%,75.7603%,#11162c 79.4275%,82.8265%,#13182f 86.2254%,87.8354%,#151a32 89.4454%,91.8605%,#171c36 94.2755%,95.4383%,#181d38 96.6011%,98.3005%,#191e3a)

创造力：
linear-gradient(90deg,#1f1e23,0.77381%,#201f24 1.54762%,6.72619%,#201e23 11.9048%,12.381%,#211f24 12.8571%,27.9167%,#232024 42.9762%,51.9048%,#201e23 60.8333%,61.9643%,#1f1d26 63.0952%,66.7262%,#1c1b29 70.3571%,73.2738%,#191928 76.1905%,77.1429%,#171728 78.0952%,79.9405%,#151629 81.7857%,84.1667%,#141528 86.5476%,87.0238%,#131428 87.5%,89.3452%,#11122c 91.1905%,95.5952%,#0e0f2c)

精确：
linear-gradient(90deg,#131512,1.3089%,#121612 2.6178%,17.4084%,#111511 32.199%,36.2565%,#101511 40.3141%,45.0262%,#0f1511 49.7382%,51.8325%,#0e1514 53.9267%,57.199%,#0d1514 60.4712%,62.9581%,#0b1514 65.445%,66.2304%,#0b1514 67.0157%,68.0628%,#091513 69.1099%,75.1309%,#061410 81.1518%,82.5916%,#041310 84.0314%,84.4241%,#04130f 84.8168%,86.911%,#03120f 89.0052%,94.5026%,#02100c)

就这样~😊
