/* ============================================================
   紫光美容室 by shikou - 神戸・布引町
   Quiet violet theme. VARIANCE 4 / MOTION 2 / DENSITY 3.

   This practice works with trichotillomania (抜毛症) and hair loss.
   Restraint IS the design: deliberately the calmest site in the
   project. No reveal animations at all (MOTION 2 means hover and
   focus only), so there is no .rv class here and therefore no
   blank-page-without-JS risk to guard against.

   Theme lock: light, whole page.
   Accent lock: muted violet, taken from the 紫 in the shop's own name.
   Radius lock: 8px everywhere.

   Contrast, computed not guessed (WCAG AA needs 4.5:1 for body text):
     ink    #2b2733 on bg #f4f3f6 ........ 13.19:1
     muted  #5c5668 on bg ............... 6.36:1
     accent #6b5b95 on bg ............... 5.34:1
     accent #6b5b95 on bg-2 #eceaf1 ..... 4.95:1
     ink    on bg-2 .................... 12.22:1
     muted  on bg-2 .................... 5.89:1
     white  on accent surface .......... 5.90:1
     white  on accent hover #574a7d .... 7.83:1
     muted  placeholder on white input . 7.03:1
     warn   #8c3a3a on bg-2 ............ 6.33:1
