=== HAND-DRAWN CEL-ANIMATION WATER EFFECTS ON REAL SKATE FOOTAGE
— V2V on <<<video_1>>> (~10s, match source) ===

⚠️ SOURCE LOCK: build on <<<video_1>>> — keep the REAL plate 1:1:
the skater's identity/face, his exact riding and timing, the
camera moves and framing of every shot, and the exact EDIT: the
source has EXACTLY 4 shots with cuts at ~1.6s, ~2.9s and ~8.6s —
keep those cut points and DO NOT ADD any new cut, transition,
dissolve, flash, or re-cut anywhere. The third shot (~2.9-8.6s,
containing the slow-motion ollie, the landing and the carves) is
ONE CONTINUOUS unbroken take — keep it that way, including its
speed changes. Do not alter the street, the sky, the light, or
his body. Only ADD the 2D water effects layer.

🌊 THE EFFECTS — 2D HAND-DRAWN CEL ANIMATION WATER, HUGE SCALE:
All water is flat, hand-drawn 2D animation in the style of
Japanese effects animation: bold graphic wave shapes, clean
thick outlines, flat fills with simple two-tone shading, white
foam drawn as crisp graphic curls and dots, stepped cel-style
motion (animated on twos). NO photorealistic water, NO fluid
simulation look, NO 3D renders. Color palette: deep OCEAN BLUE,
electric CYAN, and WHITE foam — bold against the real blue sky
and gray asphalt. The 2D water is perfectly TRACKED to the real
3D positions: bursts stick to the asphalt where they erupt,
trails lock to the wheels, airborne water holds its position in
space as the camera moves. Water never covers his face. GO BIG:
every splash is oversized and theatrical — but it appears and
resolves fast, never lingering long enough to hide him.

SHOT 1 (wide follow-cam, 0-1.6s): each PUSH — the instant his
shoe strikes the asphalt — erupts a cel WATER COLUMN from the
contact point, twice his knee height, with graphic foam curls
at the top and fat droplets flying. Twin wakes of drawn water
peel off the wheels like a speedboat, running along his path.

SHOT 2 (feet close-up, 1.6-2.9s): the hero eruption: his push
foot slams down and a MASSIVE cel splash detonates under the
sole — a wide graphic crown of water filling the lower frame,
white foam curls, fat droplets frozen mid-air for a beat in
cel style — while the wheels cut through drawn water like a
boat hull, spray fanning off both sides.

SHOT 3 (one continuous take, 2.9-8.6s) — tie every effect to
his MOTION, not to fixed times:
- as he crouches and POPS the ollie: the twin wheel-wakes
  SURGE up into a spiraling column of water that launches him
  like a geyser.
- during the SLOW-MOTION air: the water goes slow with the
  footage — a huge ribbon of cel water spirals around him and
  the board, breaking into orbiting spheres and arcs of blue
  and cyan, fat droplets and foam curls hanging around his
  silhouette against the sky. He rides inside his own wave.
- at the LANDING, the instant the wheels slam down: everything
  CRASHES — the orbiting water gets yanked down into the
  impact and detonates as a giant radial TIDAL RING sweeping
  outward across the asphalt, with a second crown splash
  jumping back up behind him. The biggest moment of the video.
- during the two quick CARVES: each carve throws a huge
  surf-style cutback spray — a tall graphic fan of water off
  the board's side, deep blue for the first carve, cyan for
  the second, foam flying — like a surfer slashing a wave.

SHOT 4 (riding toward camera, 8.6-10s): the twin wakes stream
toward the lens, drawn spray whipping past the frame edges;
when he throws his arm out wide, he drags a curtain of cel
water up with his hand, scattering fat droplets toward the
camera; as he blasts past, one last graphic wave crashes across
the lower frame and dissolves into foam dots. End on a few
droplets falling in cel style.

AUDIO: keep the real skate foley — wheels on asphalt, the pop,
the slam of the landing — and layer bold, anime-style water
sounds on top: deep whooshes, big theatrical splashes, a
wave-crash on the landing, playful drips on the small hits,
each synced exactly to a visual burst. Huge and fun. No music.
