   Bay Vista Construction - shared site styles
   One stylesheet for every page (no build step). Pages add small
   page-specific <style> blocks only when a section is unique to them.
   Palette mirrors the BVC brand; type mirrors bayvistapm.com
   (Libre Baskerville + DM Sans) so the two sister sites read as one family.
