Streakly

One dark set is built first and rises the way a streak does (relief tiles, a podium, a flight of stair blocks, cube columns, a summit), and every cut moves to a new corner of that same world while the camera comes to the glass on the feature beats.

A satin-walled corner room holding a relief-tile plaza with lit discs, a plinth with three glowing rings, a flight of nine stair blocks with lit nosings and columns of stacked cubes, raked by blind-shaped bars from a high window, with a cool rim on the back wall and dust in the light. A moody 42.7 s piece at 96 bpm in five long beats of 7-9 s, ending on a crane back as every stair lights to the top.

    REF-MA-04 · BUILT SET — "One small win every day."  A ~43 s promo for STREAKLY, a habit + wellbeing
    tracker (fictional; no real brands). Reinterprets a stock "3D mobile app promo" template:
    one dark set built FIRST — a relief plaza, a podium by a column, a flight of stair blocks, a
    cluster of cube columns, a summit of plinths — and every cut moves to a new corner of that same
    world. What the reference lacked is fixed: the screens are a real app and the camera comes to the
    glass on the feature beats, where the app carries the story; the world answers what the app does.

    WORLD  1 unit = 1 mm. Floor y 0. A corner room: back wall face z -3000, left wall face x -4500,
           graphite surfaces, one high window off-frame right (a blinds-cookie spot raking diagonal bars
           of light across the set: the reference's light shafts), a cool rim bar along the back wall.
           The set rises the way the streak does (blocks rising day by day), built at room scale; the
           app's mark (three growing dots on a diagonal, a streak of check-ins) sits on the summit:
             plaza    (S1)  x 940…3660  z -460…2260   25 relief tiles, iris/blush/sky discs; hero disc
             podium   (S2)  (-2600, 0, -1500)         r 330 × 560 plinth, three glowing rings on its top
             stairs   (S3)  x -2000…1600 against the back wall, 9 blocks 180 mm a step; a lit nosing per
                            day of the streak (0–3 lit; S3 lights 4 and 5; S5 lights the rest)
             cluster  (S4)  x 2100…3630 z -2550       7 columns of 240 mm cubes = the week's bars
             summit   (S5)  (-150, 0, 700)            three plinths: the phone, the rings, the mark
           Palette (set + app): violet-graphite #2c2a33 / wall #33313a / floor #211f27 · iris #9370ff
           (Body, the brand) · blush #ffa8d2 (Goals, the streak) · sky #4fb6ff (Calm) · ink #f3f1fa.
           App UI: ground #0c0b12 · surface #17151f / #201d2a · line #2d2a3a · muted #a6a3b8. Lights tinted
           lilac (window #f6f0ff, rim #d6c7ff, practicals #b9a2ff / #a98cff).

                                   relief plaza, the phone flat on the iris disc; its screen ASSEMBLES
                                   (ui-assemble: four layers fly in, hover as a staircase, pack home)

                                   past the column onto the glass: three dotted rings fill, Calm closes,
                                   then the podium's three rings light in answer

                                   flight, a habit checked (the next nosing lights), the composer GROWS

                                   the cube columns rise behind the phone with them; the streak card lands

                                   lockup on the wall
    Shot budget: on a screen node 29 % of the reel by the repo's screenShare measure (s2 2.8–6.4, s3 3.6–8.1,
           s4 4.5–8.3, travel included); everything else is the world; ONE ultra close-up (s3, hb-shell fill 165 yaw −50).
