+===============================================================================
+
+CURRENT IMPLEMENTATION STATUS
+
+This spec covers two related but distinct pieces of the 02_text_description component:
+
+A. Text renderer engine
+   Files: include/02_text_description.h, src/02_text_description.cpp
+   Status: COMPLETE
+
+   Implements the TextRenderer class using FreeType. Loads printable ASCII glyphs
+   (codes 32-126) from a TTF font into individual GL_RED textures and renders them
+   as textured quads into whichever viewport is currently active.
+
+   Public methods:
+     initialize_shaders()        — compiles/links shaders/02_text_description_{vert,frag}.glsl
+     initialize_font(path, size) — loads a TTF font at a given pixel height
+     render_text()               — renders a string at a viewport-local pixel coordinate
+     render_text_wrapped()       — renders with automatic word-wrapping at a max pixel width
+     get_text_width()            — returns the pixel width of a string at a given scale
+     set_projection(w, h)        — sets the orthographic projection for a viewport
+     cleanup()                   — releases all GL resources and glyph textures
+
+   Two global instances are defined in src/02_text_description.cpp and declared
+   extern in the header:
+     g_text_renderer        — loaded at FONT_SIZE_NORMAL (body text, controls, status bar)
+     g_text_renderer_large  — loaded at FONT_SIZE_TITLE  (panel titles, scope headings)
+
+   Font path and sizes are defined in include/settings.h:
+     FONT_PATH         "/usr/share/fonts/truetype/dejavu/DejaVuSans.ttf"
+     FONT_SIZE_NORMAL  18 px
+     FONT_SIZE_TITLE   26 px
+
+B. Left-panel text content for each radar
+   File: src/01_classes.cpp (render_left_panel() methods in each radar subclass)
+   Status: STUB — text content implemented; actual scope rendering is not yet done.
+
+   Each radar subclass in 01_classes renders:
+     - Radar title (large renderer, white)
+     - Location sub-header (small scale, white)
+     - 3-4 lines of description text (white)
+     - "--- CONTROLS ---" header (red) followed by per-control entries
+       (label in red, keystroke(s) in pink, on the same line)
+     - "1 - Return to Radar Selection" (yellow)
+
+   The intro scene (item 5 above) is rendered by render_intro_left_panel() in
+   src/main.cpp, which shows a welcome paragraph on the left panel and the
+   radar selection list centred in the scope viewport.
+
+   Status bar content for each radar is rendered by render_status_bar() in
+   src/01_classes.cpp, displaying current uniform values (intensity, sensitivity,
+   STC sensitivity/range, and radar-specific values such as max range, cursor
+   positions, radiogoniometer, or antenna bearing) in yellow.
