A reusable implant-layer busy indicator (Araminta's spec): an animated
bracket sweep `[ >>>>···· ]` with a caption, themed entirely via ImplantTheme.
The Atlas shows it centered over the canvas while the Layer-1 proxy is Pending
and hides it on Ready — so cache hits never flash it and serverless mode never
shows it.
Layer separation (per direction): ImplantPending belongs to the diegetic
implant UI only. The global, non-diegetic UI layer must use its own busy
indicator with its own visuals — sharing the sweep logic is fine, resting on
this theme/these glyphs is not. Documented in the component header.

Render the proxied Layer1Output (D-225) as toggleable Atlas overlays. The
viewer stores the decoded Layer1Output via set_generation_layer1() and the
marker overlay draws three new layers gated by their visibility flags:
RVR river_cells as dots, confluences as small circles, mouths as
double-ring sea-terminus markers
BAS drainage-basin boundaries as thin closed polylines + faint fill
ATR geographic attractors — shape by attractor_type (Araminta's 7-shape
vocabulary), color by sub_biome, size by strength; <0.15 culled
Layer-1 positions are [row, col] in the 512x256 working grid, which matches
the viewer's grid_to_canvas transform, so they project directly onto the
heightmap. OVERLAY_DEFS gains gen_l1_rivers/basins/attractors (toggle group)
so AtlasOverlayBar auto-exposes them as toggle buttons.
