The home hero of the Sivali Corp site: a full-height `#121212` stage with the animated logo lockup top-left, eyebrow, H1, bold-led lead, accent + ghost buttons and a frosted stat bar at the bottom.

- Background: the live site renders a Jakarta skyline as 3D line art (Monas centre, indigo grid, mint pulses travelling between towers) with a left-to-right `#121212` fade for legibility. This preview stands in with dotted orbit rings; any background must keep the left 60% dark enough for white body text.
- Lockup: `SivaliMark.draw` at 96 to 140px (`clamp(96px,10vw,140px)`), glowing; on scroll it shrinks and travels into the header logo slot.
- Type: eyebrow 12px tracked 0.18em in `#ADFCB9` · H1 `clamp(40px,4.4vw,60px)`/1.06 Medium, tracking -0.025em · lead 17px/1.65 `#DBDBDC` with the opening clause in Bold white.
- Buttons: accent mint (`#ADFCB9` on `#015B6A`) for the one primary action, ghost glass for the secondary.
- Stat bar: see StatBar.

Alternative "split" hero (yin-yang): indigo left half with `border-radius:0 0 280px 0`, photo right half with `280px 0 0 0`, white and indigo dots marking the two eyes.
