/* Responsive layer for the Alchemist Media Labs site.
 *
 * The pages are exported from Claude Design with every style inline, so this
 * file can only win with `!important`. Where a rule targets a specific block it
 * keys off the exact inline `style` string ([style*="..."]) — if a page is
 * re-synced from the design and those strings change, re-check this file.
 *
 * Breakpoints
 *   ≤ 900px  tablet: narrower gutters, two-column heroes/sections stack
 *   ≤ 760px  hamburger navigation, three-column card grids stack
 *   ≤ 640px  phone: 20px gutters, tighter type and spacing, list rows re-flow
