/* ==================================================================
   STYLES — "Moody West Coast Timber Guild": dark, warm, lantern-lit.
   Deliberately distinct from both the main Acuity site (navy/copper/
   Playfair) and the Auto Estimator demo (cool cyan/near-black/Rajdhani)
   — warmer and earthier than either. Layout (spacing/grid/flex/
   breakpoints) is handled by Tailwind utility classes in index.html.
   Everything here is either global dark-theme chrome or a component
   whose color comes from the --accent custom property (set at runtime
   from js/config.js), so re-skinning never requires touching this file.
