/* Three Alarm Ventures: site stylesheet
 *
 * One file, no framework. Sections:
 *   1. Fonts and design tokens      5. Header and navigation     9. Pages: services, approach, about
 *   2. Base and typography          6. Hero                     10. Contact form
 *   3. Layout helpers               7. Shared components        11. Footer
 *   4. Buttons and links            8. Home page sections       12. Utilities, motion, print
 *
 * Colour rules worth keeping: white text sits on --red-600 or darker (never --red-500),
 * orange is decoration only (never text on a light background), and the photographic
 * emblem is only placed on the dark backgrounds it was cut out for.
