Launch video remake comparison

white page above a black laptop bezel band (y425–475, top highlight #686866), a dark navy menu bar (y477–538), wallpaper below = the blue sky gradient with thin white line art (one big circle, two horizontal lines, one vertical, a four-point sparkle at a crossing, soft teal glow top-right). Menu bar right cluster in white: Wi-Fi, battery, toggles, the product mark at x531–584, three ⌀36 dots #2F6BFF / #3CC8F0 / #4ED6A0 at x612, 661, 709, "Mon Jun 22  9:41 AM" 34 px. Enters blurred 3 px and settling by f110. Cursor rises from below (f102), sits on the mark, presses f113–117. Camera pans content right +125 px f115–130 (fastest f118–120). A frosted glass box (white-blue glass over the sky, bright top rim, radius 60) springs out from under the mark f116: width peaks 744 at f126 and settles 726x228 by f138 around x196–922, y568–797. The prompt types from f121 (first legible "Make ") to f150 (complete) at about 1 char/frame with a 1-frame hold every 2–3 chars; caret always on; three white outline icons along the bottom; send button #2F6BFF ⌀51 with a white up arrow. From f136 the whole scene drifts up, accelerating into a whip-tilt (f158 moving ≈25 px/frame, vertical blur ≈6–8 px) while the page tints #E6F4FE over f154–158.
S4 f159–186, answer page: a light course lesson page (breadcrumb, title, body): text column x120, body 47 px Inter 400 grey #BCBCBA, line pitch 58, one key phrase ("frame for frame") in black 600. It arrives smeared and 420 px low, scrolls up with offsets 420, 315, 210, 170, 140, 116, 96, 81 (f166) … 14 (f175) … 0 (f180), then creeps −6 px by f186. Blur 24 px (f159) → 1.5 (f165) → 0. Flash #E2F4FE fading to #FDFDFB by f165. A cursor pointing straight up rides the scroll and stops under the key phrase (≈(450,591) f180), then drifts right.
S5 f187–214, card: a white card (x203–878, runs off the bottom) rises over the page: cover image 627x536 inset 24 px, radius 64, a light grabber bar at its top centre, caption semibold 38 px black, sub-caption grey 23 px. Cover top y642 (f187) → 456 (f191) → 395 (f196) → 369 (f200) → 348 (f205), then keeps drifting up ~4 px/frame. Card blur peaks 3.8 px at f189, sharp by f201; the page behind blurs to ≈2.5 px. Exit f207–214: card shrinks ~5% and rises while the whole frame blurs 1 → 7 px; cut at the blur peak.
S6 f215–244, two cards: white page, two stacked cards 538x348 (radius 57, gap 36) centred on x540, top card settling at y168 by f230, bottom at y552. Each: cover art (no text baked into it), a frosted pill top-left ("Module 3" / "Module 5"), a frosted round "•••" top-right, and a huge bold title along the bottom edge made of frosted glass (a blurred, lightened copy of the image clipped to the letters, cut off by the card's bottom edge): "Launch" and "Sound". Both enter blurred 12 px and sharp by f224; the top card enters 8% large and rises from y264; the bottom card rises from y927, staggered behind it. They drift up 3 px/frame f230–238, then accelerate up and blur out into the cut.
S7 f245–300, logo disc: page #FDFDFB, disc ⌀168 #F6F6F6 with the dark mark, rises into the centre (top y569 f245 → 491 f250 → 468 f255 → 456 f269) with a vertical smear on the cut frame, holds still f269–287 (the only frozen stretch), then shrinks accelerating to ⌀123 at f300.
S8 f301–359, end card: black radial background (#020204 corners, ≈#272729 around the word), the wordmark in Inter 600, white #F3F3F5 with a tight glow plus a wide soft halo, centred (540,540). Word width: ≈1650 px f301 (horizontally smeared, zoom streaks) → 1350 f302 → 1110 f303 → 1049 f304 → 734 f309 → 678 f311 → 563 f320 → 516 f342 (≈1 px/frame shrink) → 492 f350, then collapses ease-in: 450 f355 → 267 f359 with blur rising to 3.5 px. The film ends mid-collapse.
</structure>

<build>
1. One HTML page, 1080x1080, drawn by seek(t) as a pure function of the frame number. No CSS transitions, no timers, no Math.random (seeded hashes only). Shots register as {f0, f1, render(localFrame)}.
2. Every value is continuous in the frame number (the 59.94 master renders half frames): animate with keyframe tables kf(frame, [[f, value], ...], ease) and per-frame lookup tables with linear interpolation. No Math.floor on motion.
3. Blur: CSS filter blur for round blur, SVG feGaussianBlur with separate x/y stdDeviation for directional smears. Zoom smear on the end card = 20–30 scaled, faded copies of the word. Frosted glass = a blurred, lightened copy of what's behind, clipped to the shape.
4. Cursor: one SVG macOS arrow (black fill, white outline, soft shadow) with rotation and scale, reused in S1, S3, S4.
5. Sound (no voice), exactly 12.075 s: music at 124 BPM, soft intro, the drop at 2.47 s (beat 5, the f72 cut leads it by 2 frames). Synthesized SFX: soft impact 0.10 s; whooshes peaking at the cuts 2.402, 3.370, 5.305, 10.043 s; transition hits exactly on 6.240 s and 8.175 s; clicks at 2.33 and 3.83 s; very quiet key ticks every ~32 ms over 4.04–5.00 s; a soft shimmer at 10.05 s. Master to −14 LUFS, true peak −1 dBTP, no fade except the last 60 ms.
6. Render with Playwright (one screenshot per frame, fonts loaded first), encode H.264 yuv420p at 60000/1001, mux the audio.

<gotchas>
Measure text only after the fonts load. A long product name won't fit where a 5-letter name did: scale the whole lockup (disc gap, name, pill) to fit the span x474–1063, don't let the pill fall off-frame. A white orbit square vanishes on the white page without a 1px edge and a faint shadow. Don't put images with their own text inside the S6 cards, or the glass title doubles up. Keep the cut frames exact even where they don't sit on a beat. Nothing freezes except S7 f269–287. Heavy blur tables can wipe a shape out completely: if a frame looks empty, lower the blur until the shape still reads.

<start>
Ask me for the inputs. Then show me 4 stills (f40 header in the window, f86 icon cross, f150 finished prompt, f230 the two cards) before you render the full film.
