Would it make sense to have a common style sheet for all zoom levels?
This would make maintaining a consistent rendering styles across zoom
levels a lot easier, IMHO.  If syles need to be different at different
zoom levels they could have different names (classes).

Example:

style.css:
.highway-motorway-casing                { stroke: #222222; }
.highway-motorway-casing-z12            { stroke-width: 22px; }
.highway-motorway-casing-z13            { stroke-width: 16px; }
.highway-motorway-casing-z14            { stroke-width: 5.1px; }
.highway-motorway-casing-z15            { stroke-width: 5.1px; }
.highway-motorway-casing-z16            { stroke-width: 3.8px; }
.highway-motorway-casing-z17            { stroke-width: 1.9px; }

osm-map-features-z12.xml:
<rule e="way" k="highway" v="motorway">
    <area class="highway-casing highway-motorway-casing highway-motorway-casing-z12"/>
</rule>

osm-map-features-z13.xml:
<rule e="way" k="highway" v="motorway">
    <area class="highway-casing highway-motorway-casing highway-motorway-casing-z13"/>
</rule>

osm-map-features-z14.xml:
<rule e="way" k="highway" v="motorway">
    <area class="highway-casing highway-motorway-casing highway-motorway-casing-z14"/>
</rule>
