Frontend Integration & Future Backend Plans

Completed Frontend Integration (Phase 1 + Post-Iteration)

Frontend integration has moved from initial replacement work into production-level UX iteration.

Homepage: app/views/pages/home.html.erb with conversion-first marketing sections.
Layout: app/views/layouts/application.html.erb with adaptive mobile/desktop rendering.
Mobile frame shell: app/views/shared/_mobile_phone_shell.html.erb for signed-in app-like flows.
Dialer shell: app/views/shared/_iphone_dialer.html.erb embedded in mobile and desktop dialer contexts.
Styles: app/assets/stylesheets/application.tailwind.css using light blue action-blue branding.
Interactivity (Stimulus):
- twilio_dialer_controller.js: call lifecycle, keypad, rates preview, and hangup handling.
- country_select_controller.js: searchable country selector.
- calculator_controller.js: rates calculator interaction.
- navbar_controller.js + mobile_menu_controller.js: navigation state for responsive and in-frame usage.

Light theme harmonized across user-facing pages.
Mobile signed-in UX remains strict app-like frame.
Mobile signed-out /home now shows full marketing content for conversion.
Sign-in and magic-link confirmation screens are integrated into the iPhone-frame visual language.
Rates page mobile behavior stabilized (frame alignment, button placement, select readability, toggle highlight consistency).
Twilio dialer hangup/cancel flow hardened for Safari/mobile reliability.

Rates calculator is already connected to backend rate APIs.
Twilio voice and status webhooks are validated server-side and processed asynchronously.
Call/billing state is persisted in backend models and surfaced in UI history/rates contexts.
