fix(store): render feature-graphic wordmark with real font (Titan One, OFL)

The flutter_test default font draws every glyph as a box, so the wordmark was
unreadable. Load the OFL Titan One TTF via FontLoader in the generator and
render 'Block Seasons' + tagline with it; fit the text within the 1024 width.
Font used only by the asset generator, not bundled in the app.
