In the Socials drawer, under the show/hide switch: text colour, an optional background plate with its own colour and opacity, and a text drop shadow. The bar had been hard-wired white-on-transparent since it shipped. - `SocialsConfig` gains five additive properties (BarTextColor, BarBackgroundEnabled, BarBackgroundColor, BarBackgroundOpacity, BarTextShadow). - Persistence: five new Socials columns, added by the per-column idempotent migration pattern (a half-migrated DB heals instead of failing), written in Save and read back in Load with defaults for pre-existing rows. - `SocialBarRenderer.Render(entries, SocialBarStyle?)` — the look is a separate value type so the renderer stays a pure "entries + look" function and the preview can never read a half-applied config mid-edit. A malformed hex falls back to white/black instead of throwing inside a render tick. - The plate hugs the entries (rounded 20px, padding) so it reads as a caption bar, not a band across the frame. Off by default, because transparent is what creators have today. - The colour pickers reuse `BorderColorPalette` — one catalogue of the app's colours, per the TASK 60/63 rule. Guard: SocialBarAppearanceTests paints the real strip and inspects pixels — default is white with no plate, a red text colour reaches the glyphs, a 55% blue plate yields half-transparent blue pixels, and the shadow adds dark pixels that were not there before.
