driveAtlas: redraw large1 as a Rosewill RSV-L4500U cutaway

Lint / Shell (shellcheck) (push) Successful in 9s
large1 lives in a Rosewill RSV-L4500U 4U case, not a generic "3x5 grid". The old render was a plain placeholder that said little about the machine. This chassis is awkward to draw honestly: the drives are NOT visible from the front. The full-width perforated door drops down to reveal a wall of 120mm fans, and the 15 bays sit behind it in three removable 5-drive modules serviced by taking the TOP COVER off. So a literal front elevation would show zero drives. Draw a front elevation with the fan wall and dust door CUT AWAY instead: the chassis silhouette stays recognisable - rack ears carrying the big vertical D-handles, the perforated drop-down door with its centred barrel lock, the slim right-hand I/O strip - while the cutaway (dashed tear edges, ghosted arcs of the outer two 120mm fans) exposes all 15 bays. Geometry per Rosewill's manual: 3 modules side by side, 5 drives stacked FLAT in each, long axis front-to-back with connectors facing the rear. So from the front every bay is a WIDE, SHORT slot and the grid reads 5 rows x 3 columns - the inverse of the Sliger's tall on-edge slots. The chassis documents no bay numbering and has no backplane and no per-bay LEDs, so numbering is stated in the output as a driveAtlas LOCAL convention (1-5 left module top->bottom, 6-10 middle, 11-15 right) with a reminder to identify a drive by serial, plus a note that service is top-cover-off. Fixed 96-column canvas, identical display width on every line in monochrome and colour, colour runs coalesced (max 17 escapes per line, never changing inside a repeated glyph run), SAFE width-1 glyphs only.
