Adds .launcher, .launcher-tile, .launcher-hero, .launcher-grid styles
plus .brand-logo replacement for the gradient-D mark in the sidebar.
The shipped img/dragon-logo.png has a light-gray background; we use
mix-blend-mode: screen so the black dragon silhouette sits on the
dark theme without showing the gray box, and a soft accent glow under
the hero version. Smaller sidebar version uses the same trick.
- Topbar search now sits on bg-2 with a stronger border, subtle inset
highlight, and a hover state. Search icon and kbd hint get more
contrast. Focus state lifts the field with a soft accent ring.
- Search results dropdown gets a slightly inset header look so the
list reads as connected to the field.
- Right-click context menu (ctx-menu) gets a stronger background,
a tighter section header, separator color tuning, and a soft
outline so it feels like a popover instead of floating text.
Previously the responsive rule hid only .search, leaving the dropdown
positioned on its own wrapper. Target .search-wrap so input + results
both hide together.
