/*
 * Photo2Form — tool layout + macro component styles.
 *
 * Loaded by base_tool.html after common.css + components.css + the
 * tool's theme CSS. Provides:
 *
 *   - .tool-grid       — two-column settings / preview layout
 *   - .upload-form     — macro: ui.upload_form()
 *   - .param-row       — macro: ui.parameter_slider(), ui.select_dropdown()
 *   - .btn-generate    — macro: ui.generate_button()
 *   - .collapsible     — macro: ui.collapsible()
 *   - .notice          — macro: ui.notice()
 *   - .lightbox-*      — partial: partials/lightbox.html
 *   - .progress-*      — partial: partials/progress.html
 *   - .depth-model-fieldset — macro: ui.depth_model_selector()
 *
 * Everything is driven by the design tokens in themes/_base.css, so
 * swapping themes/cnc.css for themes/laser.css recolours the whole UI.
