/* ASAS - reset, typography and layout primitives (Milestone F1)
 *
 * Depends on tokens.css. Load order: tokens.css -> base.css -> components.css.
 *
 * LOGICAL PROPERTIES ONLY. `business_settings.default_language` defaults to
 * 'ar' and the conversation engine matches Arabic intent, so this is a
 * bilingual AR/EN product and RTL is a Release-1 requirement, not an
 * enhancement. Never write left/right/margin-left/padding-right/text-align:left
 * in this codebase - use inline-start/inline-end. Retrofitting logical
 * properties across forty surfaces later is the expensive version.
