/**
 * Com4thPlus Frontend Theme
 * A professional restyle of the apartment listing, single apartment, and
 * booking pages built from the actual Com4thPlus logo palette: light
 * cyan (#6FD5EC) sweeping into the brand's mid-blue (#3998C8) and a deep
 * navy (#123A5C). This file only restyles the existing markup/classes
 * already output by the original templates — no HTML, PHP, or the
 * functional date-blocking / booking logic is touched.
