/**
 * FifoConsult Custom WordPress Theme
 *
 * CSS module: BODY 03 / Project Architecture.
 *
 * Module:
 * FifoConsult — Project Architecture / From Vision to System.
 *
 * This stylesheet controls the visual presentation of the third BODY
 * storytelling section on the FifoConsult front page. It defines the dark
 * atelier environment, left-side method content, right-side Renaissance Method
 * Canvas stage, sequential PNG fade behavior and large BIG picture popup.
 *
 * Purpose:
 * The Project Architecture module visually explains how FifoConsult turns an
 * initial project idea into a structured digital system before design and
 * coding. The visual language is intentionally cinematic, calm, premium and
 * Renaissance-inspired, avoiding dashboard, template and generic SaaS effects.
 *
 * Responsibilities:
 * - BODY 03 full-screen section sizing and background composition
 * - dark atelier / canvas atmosphere and gradient readability layers
 * - left-side content positioning, typography and spacing
 * - kicker, section title, lead text and active paragraph styling
 * - four mode navigation buttons and active state treatment
 * - right-side PNG canvas stage positioning
 * - two-layer PNG frame system used by JavaScript
 * - image opacity transitions for sequential fade in / fade out
 * - frozen-breathing state support during PNG fade-out
 * - pause / resume click area over the canvas stage
 * - Picture 1 / Picture 2 / Picture 3 inline link styling
 * - fullscreen BIG diagram picture popup styling
 * - background blur / dim overlay while popup is open
 * - close button positioning and modal image presentation
 * - laptop / desktop safety adjustments for the BODY 03 layout
 *
 * Main visual sections:
 * - Base Section
 * - Left Content
 * - Left Navigation
 * - Right Architecture Board Stage
 * - Laptop Safety
 * - Final PNG Overlay Lock
 * - Picture Popup Links
 * - Diagram Picture Popup
 *
 * Related template:
 * template-parts/body-project-architecture.php
 *
 * Related JavaScript:
 * assets/js/body-project-architecture.js
 *
 * Visual assets:
 * assets/img/body/project-architecture/
 *
 * Main section PNG sequence assets:
 * project-architecture-vision-01.png ... project-architecture-build-03.png
 *
 * Large popup PNG assets:
 * project-architecture-big-vision-01.png ... project-architecture-big-build-03.png
 *
 * Visual identity:
 * Renaissance Method Canvas / dark atelier / gold linework / architectural
 * project logic / ART-to-SMART system design.
 *
 * Important implementation note:
 * This CSS file is intentionally separated from main.css and from the BODY 01
 * and BODY 02 styles. BODY 03 keeps its own class prefix, assets, timing
 * support classes and popup styling so it can be edited safely as a standalone
 * storytelling module.
 *
 * Concept, visual direction, structure, interface design and implementation:
