- MainHeader.js: render the main layout table at width=100% and let the
mainRightTD content cell auto-fill remaining space (left nav stays 121px).
Previously the content cell was fixed to docWidth (~480px), wasting most of
a modern wide monitor.
- standard.css: neutralize html{zoom:130%} (force 100%) and add an
#mainRightTD{width:auto!important} guard.
