/* Solanko Project Portal — single hand-written stylesheet (DESIGN §8/§8a + the
   2026-08-12 "command console" treatment). No CDN assets, no bundled fonts
   (Gridnik/Mallory are commercial — system sans, pushed with weight + tracking).
   Identity: charcoal + white + signal red, square corners, uppercase letterspaced
   headings, a monospace technical layer, and a live bathymetric-chart backdrop.

   Every declared text/background token pair below is asserted >= WCAG AA by
   tests/test_contrast.py. The --color-* names + their pinned values are the
   contract; the console layer adds tokens, never changes the pinned ones.

   Token table (light / dark):
     --color-bg               #FFFFFF / #16181B   page ground
     --color-panel            #FFFFFF / #212327   cards & panels
     --color-text             #1A1D21 / #F2F3F4   body text
     --color-muted            #4A4F55 / #A9AFB5   secondary / mono labels
     --color-border           #33373D / #33373D   hairlines
     --color-header-bg        #212327 / #212327   header/nav + status strip
     --color-header-text      #FFFFFF / #FFFFFF   text on charcoal
     --color-accent           #E71200 / #FF3B24   signal red, accent ONLY
     --color-accent-contrast  #FFFFFF / #16181B   text on filled accent
     --color-link             #E71200 / #FF4A33   underlined body links
     --color-btn-text         #E71200 / #F2F3F4   outline-button labels
     --color-focus            #E71200 / #FF4A33   focus rings
   Console layer (added):
     --color-panel-2  input wells     --color-chart  bathymetric lines (atmosphere)
     --color-ok / --color-warn  semantic state chips (separate from the accent)
