the unsung floor everything else proudly stands on while taking all the credit
means The underlying layer or surface on which something else lives, grows, builds, or reacts — the foundation beneath the action.
from From Latin substratum, the neuter past participle of substernere, 'to spread underneath' — sub ('under') plus sternere ('to spread, strew'), the same root that gives us 'strew' and 'stratum.' English borrowed it into science by the 19th century, where it became the dependable base coat for everything from biology to geology to chemistry.
