The TDS v1.2 sync removed the .lt-main.lt-container combined selector that
was already in the project's base.css. That selector has specificity (0,2,0)
vs single-class (0,1,0), so it always wins over .lt-container padding
shorthand at every breakpoint without needing per-breakpoint overrides.
Also restored flex:1, width:100%, min-width:0 on .lt-main that were dropped.
Removed the incorrect per-breakpoint .lt-main and #main-content hacks added
today which were the wrong approach to the same problem.
