-// oa/xblock: openassessment - main style compile
-// ====================
-
-// NOTES:
-// * this Sass compiles into the static CSS needed for the openassessment oa/xblock
-// * Sass partials that can be re-used are organized in the "oa/xb/" directory and listed in "general oa/xblock" segments
-// * theme-based Sass partials are noted by "theme - [theme name]" in the import order to override defaults
-// * openassessment-specific styles are collected within the "oa/" directory and listed in "app -" segment
-
-// * openassessment-based layouts are sized like media-query breakpoints, but will be applied by specific classes/variables
-// * the system/app digesting this oa/xblock will control general page layout and overall screensize-based breakpoints
-
-// --------------------
-
-// KNOWN ISSUES/CONCERNS:
-// * manual syncing of a view's breakpoints/layout with openassessment's sizes is needed on a system/app basis
-// * the system/app ingesting this oa/xblock may have conflicts/redundancies/versioning issues with the utilities used
