# UI Renderer

## Current state

`game/src/ui.rs` — procedural primitives on the RGB565 framebuffer, all clipped:
`fill_rect`, `draw_rect` (1 px outline), `draw_hbar` (value/max bar).

The HUD (`Game::render_hud` in `game.rs`) lives in the 80 px strip right of the 240×240
viewport: player name, HP bar, population counters, a divider, then the message log
filling the rest bottom-up (newest line always visible, lines wrapped to the panel).
The log is a `VecDeque<String>` fed from `Sim` events in `Game::handle_events`.

Draw order: world, then HUD. The HUD overwrites the right-edge bleed of the tile pass,
which is why there is still no clip-rect on the blit primitives.

## Open questions

- Tileset-based borders vs. line-drawing: line-drawing for now (`draw_rect`); a 9-slice
  ornament frame like `wds` has is an option once the look matters.
- Does the message log need scrolling? Not yet — `LOG_LINES` keeps 40, the panel shows
  what fits.
