/**
 * Translate an {@link Alignment} to a CSS-property record suitable for
 * HTML preview. `horizontal` → `text-align`, `vertical` →
 * `vertical-align` (table-cell semantics), `wrapText` → `white-space:
 * pre-wrap`, `textRotation` → `transform: rotate(<-deg>)` (Excel rotates
 * counter-clockwise relative to CSS) plus `transform-origin` to keep
 * the text anchored, and `indent` → `padding-left: <n>em`. `255`
 * stacked-text rotation maps to a 180° flip with `writing-mode`.
 *
 * Empty / undefined Alignment returns `{}`.
