/**
 * Rollback told as a "return to known-good" gesture inside the lifecycle
 * tile's outlined window chrome: the window is a 1px `--border-1` hairline
 * outline with no fill (tile grey showing through), anchored to the text
 * column's left edge (`left-0`, `top-5`) and bleeding off the right and
 * bottom edges with a `rounded-tl-xl` top-left corner — the same slot
 * geometry as the build and lifecycle windows. A "Version history" title
 * bar with a right-aligned `Production` mono ChipTag (its fill stepped up
 * to `--surface-6` so the pill stays legible on the grey ground) crowns
 * the window at the family's `h-12` header height, ruled by a hairline
 * divider.
 *
 * Inside, a short newest-first version rail runs down the left gutter —
 * v4 as the quiet current row (its `Current` tag on the grey-ground
 * `--surface-6` pill fill), then a plain vertical hairline connector
 * down to v3, the lifecycle timeline's spine language. v3 is the tile's
 * highlight: the node fills solid and
 * the row lifts onto a white card (`--white` fill, 1px `--border-1`
 * hairline, nested `rounded-lg` inside the `rounded-tl-xl` window,
 * `shadow-sm`) pairing "v3 · Stable · Maya Chen" with the tile's
 * strongest element, the solid Roll back button led by a small `Undo`
 * glyph inked in the button's inverse text color. A quieter v2 row
 * dissolves through a mask gradient below, implying the history continues
 * past the window's bled bottom edge — the lifecycle tile's fade device.
 *
 * The window bleeds `2rem` past the tile's visible right edge (`1.5rem`
 * under `max-lg`), so the header and body carry matching extra right
 * padding (`pr-12 max-lg:pr-10` = the bleed plus the usual `1rem` gutter)
 * to keep the Production tag and the v3 card's Roll back button fully
 * inside the visible tile.
 *
 * The rail is fully static. The connector hairlines are absolutely
 * positioned inside fixed-height spacer rows so they can extend past the
 * row box into the adjacent rows' empty gutter space, ending a couple of
 * pixels from each node — the lifecycle spine's tight node-to-line
 * clearance — without disturbing the flow layout.
