 * Hydro Shield — homepage Work Gallery section. NEW (split from the old

 * Grey-dark background — a tonal break from Why Hydro Shield's own
 * grey-dark right above it is not needed here since Why already uses
 * grey-dark; this section instead uses graphite so the rhythm reads
 * graphite(Hero)/graphite(Reviews)/graphite(Products)/grey-dark(Why)/
 * graphite(Gallery)/grey-dark(Contact) — alternating at every step.
