/* ============================================================================
 * PCMR design system — green, white, black.
 *
 * Green carries the brand and every affirmative state. White is the working
 * surface. Black is structure: the sidebar, headings, rules, data.
 *
 * One colour outside the palette exists: --danger. It is reserved for
 * destructive buttons, validation errors and rebalance breaches — the three
 * places where a portfolio tool must not rely on a reader noticing a shade of
 * green. It appears nowhere else.
 *
 * Layout uses logical properties throughout (inline-start / inline-end) so the
 * Persian right-to-left build is the same stylesheet, not a mirrored copy.
 * ========================================================================== */
