/* ============================================================
   Cape Coral Pool Restoration — Design System
   Palette: deep teal water, coral accent, warm sand neutrals
   Type: Source Serif 4 (display) + Inter (body) + IBM Plex Mono (data)
   Signature: depth-gradient rule (shallow aqua -> deep teal) used
   as a section marker, echoing the actual color shift of pool
   water from shallow to deep end. Subtle lanai-screen mesh
   texture on alternating sections nods to the screened pool
   cages present in nearly every SWFL backyard photo on this site.
