Build "SQUEEK DEEP", a polished single-player pixel-art mining roguelite (Vite+React+TS, one , static, no backend) using ONLY the original assets in this repo under public/assets, served at ./assets (see public/assets/manifest.json + DESIGN.md; asset paths there are relative to public/assets). Replace the scaffold in src/. Commercial indie polish, zero placeholder shapes.

PREMISE: You are Pip, an orange/cream Syrian hamster with a yellow miner helmet. Dig down through 6 earth layers, stuff your cheeks with seeds and gems, haul them back to the surface hoard. A REAL hamster wheel (Squeekchain API) powers the mine elevator, and every real 600s chain round settles as an earthquake that reshapes the deep.

RENDERING: internal 480x270, integer-scaled, image-rendering:pixelated, imageSmoothingEnabled=false. Camera follows player vertically (lerp 0.15). Tiles 32px. World 15 cols x 300 rows (1 row = 1 m). Below 20m the world is dark: offscreen darkness mask with radial light from helmet lamp (110px), lanterns (96px), glow worms, magma tiles (flicker). Ambient 1.0 at surface -> 0.25 at 300m. 3px dark shadow where open cells meet solid, 1px warm floor highlight (ref assets/mock_gameplay_target.png).

ASSETS (all transparent PNG, bottom-center anchor, horizontal strips):

• hamster/ham_idle(4f,6fps) ham_walk(4f,10fps) ham_dig(4f,12fps) ham_jump(4f) ham_hurt(3f) ham_ride(4f basket) ham_dig_down(4f,12fps) ham_cheeks(stage 0-3). 80x80, face right, flip for left. Make Pip ADORABLE: squash/stretch, blinks, happy hop on pickup, cheek wobble.
• enemies/mole_shade, root_beetle, glow_worm, crystal_bat (play 0,1,2,1), magma_slug: 3 frames each, 72x64, face LEFT.
• tiles/tiles.png: 3 cols x 6 rows of 32x32. Rows = topsoil, clay, stone, crystal, fungal, magma. Col0/col1 = solid variants, col2 = dug-out background wall.
• items/items.png: 16 icons 32x32 (order in manifest).
• props/: ore_seeds, ore_gems (32x32 ore overlays), rock_cracked (boulder), wheel_on, wheel_off (surface winch), lantern, beam, basket_ride_alt.
• ui/: hud_bar, shop_panel, cheek_meter, btn_gold, btn_green, btn_wood, depth_gauge, slot -> draw as 9-slice (6px border) at 2-3x.
• keyart/title_keyart.webp (title screen), share/share_bg.png (1200x630), fonts/PixelifySans.ttf (@font-face, all UI text), audio/*.ogg (see manifest). Audio unlocks on first gesture; mute saved.

CORE LOOP: Surface camp (winch, hoard chest, shop, leaderboard) -> dig down/left/right -> collect -> return (walk/jump or elevator basket) -> deposit at chest (coin sfx, seed shower) -> upgrade -> dive deeper. HP 0 = run ends, cheek contents lost. "Retire" button at surface ends run safely. Score = deposited hoard + maxDepth*5.

CONTROLS: Arrows/WASD move+dig (hold into solid tile; Down/S digs down), Space/W/Up jump (coyote 90ms, buffer 120ms, variable height), E spit, Q call basket, Esc/P pause. Touch (show only when pointer:coarse): d-pad bottom-left, A=jump, B=spit bottom-right, basket button top-center, pause top-left; buttons >=56px, touch-action:none.

LAYERS (depth m / hits to break / ore% / loot / enemies):

Topsoil 0-40 /1/10%/ seeds / beetle. Clay 40-90 /2/12%/ acorn, walnut, amber / beetle, mole. Stone 90-150 /3/12%/ gold, fossil, emerald / mole, worm. Crystal 150-210 /3/16%/ sapphire, amethyst, shard / bat, worm. Fungal 210-260 /2/14%/ ruby, amethyst, rare chest / bat, mole. Magma 260-300 /4/18%/ magma_heart, ruby / slug, mole. Caverns from 120m (value noise >0.68). Lantern every ~25m, beam at layer borders, boulders need Pickaxe lvl3. Daily run seed = hash(UTC date) so all players share the map.

CHEEK MECHANIC: capacity 10 (+5 per upgrade, max 35). Weights: seed 1, nut 2, gem 3, magma_heart 5, chest 6. r=load/cap. Stage 0 <25%, 1 <60%, 2 <90%, 3 >=90% (HUD portrait = ham_cheeks frame; sprite scaleX 1+0.06stage). Speed 96px/s(1-0.35r), jump*(1-0.25r), dig time*(1+0.2r). Full = "Cheeks full!" + squeak. Item values in DESIGN.md, x(1+depth/150). Taking damage spills 30% of load as bouncing pickups. Spit(E) drops all load: +60% speed 2s, knockback adjacent enemies. Heart +1HP. Battery = +20s basket charge.

UPGRADES (persist; Daily = base stats): Cheek Stretch, Pickaxe (lv3 breaks boulders), Helmet Lamp, Fur Armor (base 3 HP), Wheel Winch, Lucky Whiskers; prices/levels in DESIGN.md.

ENEMIES: Root Beetle (1HP, patrols, turns at edges, dies to stomp or dig swing). Mole Shade (3HP, ghost through soil, alpha 0.85 purple tint, drifts toward player <160px, telegraph frame1 0.6s then lunge 220px/s 0.35s, avoids lantern light). Glow Worm (2HP, crawls walls/ceilings, drops slime every 3s, is a light source, drops amber). Crystal Bat (1HP, sleeps until player <120px, sine swoop, returns after 3s). Magma Slug (4HP, 2 dmg, burning trail 2.5s, stomp-immune). Player: 1.2s i-frames blink, knockback 140px/s, hurt frames. Dig swing deals 1 dmg. Spawn 1 enemy per 12m + 1 per quake survived.

REAL WHEEL (fetch with 4s timeout): poll https://api.squeekchain.com/v1/status every 5s and /v1/economy/state every 30s. coreStatus ACTIVE -> wheel_on sprite, sparks, basket available, +10% light, power_on sfx on transition; IDLE -> wheel_off, basket only with battery charge, power_off sfx; COUNTER_FAULT or error -> treat as IDLE + small "wheel signal lost" chip. RPM = measurement.rpmMilli/1000 in HUD; basket speed 60+min(rpm,600)*0.4 px/s; winch spin speed follows rpm. EARTHQUAKE when builder.projected.blockHeight increases (or blockProgress/1e9 wraps >0.9 -> <0.1): 2.5s shake 6px, quake+bell sfx, 8-14 solid tiles crumble, 1-2 enemies spawn, +6 ore re-seeded in dug rows. HUD "ROUND m:ss" = (1-blockProgress/1e9)*600s. Camp board shows supply.totalMintedBaseUnits as "Squeek minted". PRACTICE MODE: simulated API (ACTIVE 300rpm, quake every 90s), offline, unranked.

WALLET (optional): Connect via window.ethereum eth_requestAccounts, then personal_sign "Squeek Deep sign-in\nAddress:..\nNonce:..\nTime:..". Show 0xabcd…1234 as name (or typed name). Results screen "Record run on Sepolia": switch to chainId 0xaa36a7, send 0-value tx to self with data = hex("SQDEEP|v1|score|depth|date|seedHash"), show tx hash + sepolia.etherscan.io link, store with entry. Never mainnet, never private keys; declining never breaks anything.

LEADERBOARD: localStorage "squeekdeep.v1.lb", top 20, tabs All-time / Daily / Practice; entry {name,addr?,score,depth,hoard,date,txHash?}. Save "squeekdeep.v1.save" (upgrades, hoard, settings). Camp greeting remembers last run ("Back again! Last time you reached 142m").

SHARE CARD: offscreen canvas 1200x630, draw share/share_bg.png, text only in x470-1160 y60-570: gold "SQUEEK DEEP", DEPTH, HOARD, best haul, wheel status, date, Pixelify Sans with dark 3px outline (layout like share/share_card_example.png). Buttons: Download PNG, Copy image, and open https://x.com/intent/tweet?text=... ("I dug {depth}m deep and hoarded {hoard} seeds in Squeek Deep, powered by a real hamster wheel on @Squeekchain #SqueekDeep {url}").

SCREENS: Title (key art cover-fit; Play, Daily, Practice, Leaderboard, How to play, Credits) -> Camp -> Run -> Results. HUD: top-left wheel chip + round timer + depth; top-right cheek_meter (fill inner area green->yellow->red, portrait by stage); bottom-left hud_bar with item icons and hearts; right depth_gauge. Juice: layer-colored dig particles, 40ms hit-stop, pickup magnet 24px, number popups, screen shake. Credits: font Pixelify Sans (OFL). No fake copyright text.

ACCEPTANCE: 60fps on mid phone, no console errors, every feature above working, works offline.
