The Sivali Corp logo animation from the website hero, cut as a video bumper: the orbit dots fly in and settle, the mark fills and glows, then slides left as `SIVALI CORP` reveals. No tagline and no eyebrow: the lockup stands alone.

Timeline (intro, 4s): 0 to 1.3s dots assemble and spin down · 0.6 to 1.4s mark fills with a `primary-100` halo · 1.35 to 2.1s mark slides left, wordmark reveals · hold · 3.55 to 4s fade to ground. The outro adds the URL at 2.6s and fades to `#121212`.

Render more from code: `SivaliMark.bumper(ctx, W, H, t, { mode, theme, word, url })` is a pure function of time, so any size can be rendered frame by frame (themes `dark`, `indigo`, `light`, or a theme object `{ bg, ink, glow, accent, end, halo }` for co-branded reels in a partner's colours). Never add a tagline or eyebrow line under the lockup. Keep the bumper unedited: no speed ramps, no recolouring, no music hits that cut the fade.
