1. A computer-implemented method comprising: determining an available memory threshold associated with a device on which digital content is to be pre-cached in memory; displaying a central content set to a user, wherein the central content set is one of a plurality of content sets that, collectively, define a digital asset; identifying a first subset of the plurality of content sets that, when pre-cached in memory on the device, consume a first quantity of memory, wherein the first quantity of memory is less than the available memory threshold; pre-caching the first subset of the plurality of content sets in memory on the device; detecting that the available memory threshold has been modified, wherein the available memory threshold is modified in response to interaction by the user to display a portion of the digital asset different from the central content set; in response to detecting that the available memory threshold has been modified, identifying a second subset of the plurality of content sets that, when pre-cached in memory on the device, will consume a second quantity of memory, wherein the second quantity of memory is less than the modified available memory threshold; and pre-caching the second subset of the plurality of content sets in memory on the device.
