/*
 * Fluvia FZC — the parent company's one page.
 *
 * The visual system is Extracto's, inherited rather than invented: the tokens
 * below are copied from `frontend/src/app/globals.css` so the two sites are
 * recognisably one company's work. Three rules carry most of it:
 *
 *   1. HAIRLINES, NOT ELEVATION. 1px borders, square corners, warm off-white.
 *      No shadow, no radius, no gradient on a component. A card is a rectangle.
 *   2. CELLS, NOT CONTROLS. A control inside a ruled bar is a cell OF that bar:
 *      full height, one leading hairline, closed by the bar's own edges. One
 *      filled action per bar; everything beside it loses its box.
 *   3. ONE AMBER, RATIONED. `--color-accent` is a FILL (the action).
 *      `--color-accent-ink` is the amber things are DRAWN with (marks, text),
 *      and it is the only one that ever sits on the page ground — the fill is
 *      too light against off-white to carry a glyph.
 *
 * Logical properties throughout (`inline-start`, `padding-inline`, `border-s`
 * equivalents), because /ar/ is the same stylesheet in RTL and a physical
 * `left` is a defect the moment the page mirrors.
