/* ============================================================================
 * Salmista.com — sitewide stylesheet.
 *
 * Per §6.1 of CLAUDE.md, every page eventually loses its inline <style> block
 * in favor of (a) this shared file plus (b) page-specific overrides loaded
 * via cache-busted asset URLs from app/config/site.php's asset_version.
 *
 * Goal of this file:
 *   - Theme variables (the single source of truth for site colors/spacing).
 *   - Reset + base typography (matches the Inter font the site has used).
 *   - Common component primitives (.card, .btn, form inputs) that every page
 *     can rely on without duplicating CSS.
 *
 * Out of scope for this iteration:
 *   - Page-specific layouts (homepage hero, search results, studio timeline).
 *     Those stay inline in their own files for now.
 * ============================================================================ */
