SimTower → custom art: replacement coverage audit

41-frame 16×24 resident walk strip extracted from PE bitmap 1100. No dedicated walk cycle in OpenSky; OTSpritelistv2 characters are a usable base but need walk-frame derivation.

8 named vendors (burgers/chinese/coffee/icecream/pizza/sushi/tacos/yogurt) but night-only single-state 256×48 each. Missing: day states and the seated-diner crowd frames the sheet's later columns provide (ISSUE-037 diner overlay).

6 restaurants + pub (768×96 HD interior) — night-only, no day/empty/crowd states, no seated-diner frames. Restaurant background state pre-renders diners from the sheet today.

Only the EMPTY state (400×144). SimTower sheet 1400×60 includes filling/active states drawn as trash accumulates — fill states missing.

Car interiors exist (local/hydrolic 52×56) but only as single empty cars: missing the 5 crowd-fill states and red 'F' full indicator. Shaft art (elevatorshafts.png, 368×364 vertical) doesn't match the horizontal 140×30 shaft+machinery strip layout.

Service car exists (52×56); crowd states + F indicator missing, same as standard.

Express/large glass cars (84×56) match; crowd states + F indicator missing.

Narrow shaft strip (224×36, motor/pulley frames) — elevatorshafts.png is a vertical composition; needs recut/redraw of the horizontal machinery band.

Wide shaft strip (336×36) — same vertical-vs-horizontal mismatch as narrow.

Single empty space tile (64×48). Missing: parked-car color variants and the red-X blocked marker (20 frames in the original 480×24 strip).

Ramp corridor art exists (256×192 composed w/ EXIT signage) but original 384×24 is 16 animated car-transit frames incl. blocked-X — animation frames missing.

Generic 4-colorway walker sheet (96×120, 16×24 frames). OTSpritelistv2.png (256×256) is the key lead: ~60 character sprites at 2× (guests, families w/ strollers, bellhops w/ luggage, waiters, guards, doormen, kids, dogs). They are mostly 1–2 POSED frames, not walk cycles — deriving 6-frame walks (item.js generic cycle) and activity pair-frames is the work. Cut + downscale to 16×24 frames.

Office worker multi-activity pairs (sit/type/idle). White-collar seated poses absent from OTSpritelist; business-suit standing figures usable for idle/walk only. OTSpritelistv2.png (256×256) is the key lead: ~60 character sprites at 2× (guests, families w/ strollers, bellhops w/ luggage, waiters, guards, doormen, kids, dogs). They are mostly 1–2 POSED frames, not walk cycles — deriving 6-frame walks (item.js generic cycle) and activity pair-frames is the work. Cut + downscale to 16×24 frames.

Resident walk strip; fallback today = people.png. Casual-clothes sprites available in OTSpritelist.

Guest activity pairs; bellhop/suitcase sprites exist in OTSpritelist (perfect fit), sleep/bed poses missing (see ISSUE-037).

Waiter + diner activity frames; OTSpritelist has waiter-with-tray poses ✓, seated diners ✗.

Maid activity frames; closest OTSpritelist figures are apron dresses — usable but not a maid uniform. Icon-Housekeeping exists for the toolbox.

Security guard pairs; OTSpritelist HAS guard-with-flashlight figures ✓ (red + dark uniforms). Best-covered staff type.

Party/event guests; party-dress figures exist, dancing pairs don't.

OT_skyline.png (1024×629) is a full backdrop scene incl. ground band; the game needs a 96×55 tiling strip — crop/retile from the upper building band.

Entrance awning strip ('OPEN' canopies, 112×36). MM_awning-blue (108×62, red+blue awnings) is a close cousin; recut into 2-tile segments.

~40 named 48×48 item icons cover nearly every buildable (incl. OT-only extras). Work = downscale to the 32×24 grid cells, add the hand/magnifier hover+selected states items.png carries, and fill missing ones (housekeeping ✓, recycling ✓…).

6 micro-icons (pointer/open-hand/magnifier×2, drag, bulldoze). Icon-Bar (arrow/hand/magnify) + Icon-Garbage cover the semantics at 48×48; needs 32×21 recut + states.

Time/status bar (431×41: clock, date, Fund/Pop). GUI_Highrise-Developer.png is a full 1280×150 top bar with the same fields (12:00 AM, star row, date, funds, population, announcements) — re-slice or adopt as HUD redesign source.

Star-grid rating faces (108×132, 6 tiers × half-star steps). The GUI bar's star row gives static stars only; half-star/filled grid needs redraw.

Minimap dirt/ground band (200×24). Croppable from OT_skyline's ground band or OT_textures-2.

640×480 main-menu background with SimTower branding. OpenSky offers menu bar + 3 logos (Ocram Corp / OpenTower / Skyscraper) — a redesign, not a 1:1 swap. Web menu is DOM-based so this may simply be retired.
