/*
 * Luwara landing.
 *
 * Visual language (direction taken from Resend, not copied): pure-black canvas,
 * hairline structure, 12 to 16px radii, dense table rows with small status
 * pills, one soft light source behind the hardware, and a very large serif
 * display line against Inter body text.
 *
 * Two themes, one component set. Every colour is a role declared once per
 * theme, so a component is written once and stays correct in both.
 *
 * Measured contrast (both themes, checked with the WCAG formula):
 *   dark  ink    #F3F3F3 on #000000   18.8:1
 *   dark  body   #A9AEB0 on #000000    9.4:1
 *   dark  soft   #8B9092 on #000000    6.5:1
 *   dark  soft   #8B9092 on #0B0B0B    6.1:1
 *   dark  ok     #4ADE80 on its tint  10.2:1
 *   dark  edge   #5F5F5F on #000000    3.3:1  (control edges only)
 *   light ink    #0B0B0B on #FFFFFF   19.7:1
 *   light body   #52585A on #FFFFFF    7.2:1
 *   light soft   #5C6264 on #FFFFFF    5.9:1
 *   light soft   #5C6264 on #FAFAFA    5.7:1
 *   light ok     #0F7B45 on its tint   4.9:1
 *   light edge   #6E6E6E on #FFFFFF    5.0:1  (control edges only)
 * Section hairlines are decorative (1.3:1) and never carry meaning alone.
