/* Kevin Haggard Magic — shared app-site stylesheet
   Restyles the existing app-page markup vocabulary (.hero, .features, .feature,
   .screenshots, .cta, .card, .settings-option, .steps, .math-table, .tip,
   .effective-date, footer) in the main site's visual system.
   One file for all four app sites — replaces the per-page inline <style> blocks. */
