/* ═══════════════════════════════════════════════════════════════
   Fieldwork Electrical — concept site for the TKO portfolio.

   Warm paper, charcoal, one burnt-orange accent. Every pair below is
   measured against WCAG AA on the paper: ink 14.67, ink-2 7.19, accent
   4.92, white on accent 5.44. Accent on charcoal is 2.98 and is therefore
   never used: the dark footer sets type in paper, not orange.

   Locks, held across the page: one accent, one radius (3px), one theme.
