mix phia.undaisy (phia_ui v0.1.17)

Removes all DaisyUI references from a Phoenix LiveView project.

Automates DaisyUI cleanup so you can adopt PhiaUI cleanly. Targets configuration files and reports template files that need manual attention.

What gets changed automatically

assets/package.json — removes "daisyui" from dependencies
assets/css/*.css — removes @plugin, @import, and @source DaisyUI lines
assets/tailwind.config.js — removes require("daisyui") and daisyui: block

What requires manual migration

DaisyUI CSS classes in .heex/.ex template files (e.g., btn-primary, card-body, modal-box) must be replaced manually. PhiaUI uses function components — not utility classes — for the same UI primitives:

<%!-- DaisyUI --%>
<button class="btn btn-primary">Save</button>

<%!-- PhiaUI --%>
<.button variant="default">Save</.button>

This task scans your templates and reports every file that contains DaisyUI-specific class names so you know exactly what needs updating.

Usage
