/**
 * macOS Sequoia/Sonoma: pixel-accurate Apple system colors.
 *
 * Light surfaces: systemGroupedBackground #F2F2F7, cards on pure white.
 * Dark surfaces: #141414 (deeper than stock #1C1C1E — matches Sequoia finder/mail dark chrome),
 *   card #1E1E20, popover #2C2C2E, sidebar #0D0D0F (near-black vibrancy floor).
 * Borders: Apple uses a hairline separator — rgba(60,60,67,0.29) light / rgba(84,84,88,0.36) dark.
 *   At HSL that's ~82% L light / ~22% L dark. Kept razor-thin intentionally.
 * Primary: #007AFF light / #0A84FF dark — exact Apple systemBlue.
 * Radius: 10px (HIG standard component), 12px popovers, 20px dialogs.
 * Source: Apple HIG Color — developer.apple.com/design/human-interface-guidelines/color
