Reflect the bumped 80ms tap-feedback delay and the 350ms retry that
catches HA state syncs landing in the e-paper's busy window.

 ## Display Refresh Pattern
 Two-tier refresh wired to `lvgl.on_draw_end` via two `mode: restart` scripts:
-- **Partial** (`refresh_display`, 60ms): calls `display_partial()` — fast 1-bit, non-blocking, immediate interaction feedback
+- **Partial** (`refresh_display`, 80ms then a 350ms retry): calls `display_partial()` — fast 1-bit, non-blocking, immediate interaction feedback
 - **Full** (`full_refresh_display`, 10s): calls `component.update: display0` → `display()` — full 2-bit grayscale quality restore after idle
 
-60ms was empirically tuned: 80ms felt sluggish, 40ms intermittently raced. `component.update: display0` only pushes the frame buffer to hardware and does not re-trigger `on_draw_end`.
+The retry exists because `display_partial()` silently drops calls when the
+e-paper is still busy from a previous refresh (`waveshare_epaper_2bit.cpp`
+~line 2003). Without it, HA-triggered widget updates (e.g. fan speed sync
+arriving 200-500ms after a tap) could land during the busy window of the
+tap's partial refresh and be lost until the 10s full refresh. The retry
+fires ~430ms after the last draw, by which point the e-paper's ~300ms
+partial cycle has cleared. `mode: restart` cancels the retry if a new
+draw arrives, so it only fires in the quiet period.

-- Coordinate transform: mirror_x + mirror_y confirmed correct; swap_xy not needed
+- Coordinate transform (portrait, display rotation 0°): `swap_xy: true, mirror_x: true`,
+  calibration `x_max: 127, y_max: 295`. Gotcha: ESPHome's base class applies `swap_xy`
+  *before* calibration normalization (see `touchscreen.cpp::add_raw_touch_position_`),
+  so calibration `x_max`/`y_max` must describe the **post-swap** range — i.e., match
+  the display width/height, not the raw sensor's native axes.
