/*
 * Standalone calculators (Cv Gas/Liquid/Steam, Heating Air/Liquid/Water,

 * which rendered with NO stylesheet of their own (browser defaults: Times
 * serif, left-aligned table cells, presentational align/valign/face/bgcolor
 * attributes doing the layout).  The Conbix WordPress theme loaded for the
 * shared ESPumps header breaks all of that: it centers td text, forces its
 * Manrope font onto every element (defeating <font face> attributes), blows
 * inputs up to ~60px touch controls, and left-aligns width-limited <hr>s.
 * Everything below restores browser-default rendering inside the calculator
 * content, verified against the original pages on the old Tomcat server.
