 ## Playability
 
-**Glyphs render as boxes (□)** — symbols in the unit display, heat scale and
-conditions overlay. Cause is `spike-webswing/fontconfig.properties` (generated by
-`scripts/gen-fontconfig.sh`), which maps logical fonts to faces lacking symbol
-coverage. *Already ruled out:* trusting MegaMek's `data/fonts` removed all font
-rejections but did not fix the boxes. Next: fall back to MegaMek's bundled
-`Noto Symbols 2` / `Icons`. Verify on the unit display, not the lobby.
+**Glyphs — mostly fixed, small residue.** `scripts/gen-fontconfig.sh` now bases
+the logical fonts on DejaVu (Noto Sans covered exactly 1 of the 18 codepoints
+MegaMek uses) and adds a fallback chain of Noto Sans Symbols2 + MegaMek's bundled
+Material Symbols. Armor pips, heat pips, wind flag, direction arrow, pressure and
+light indicators all render now; verified in a deploy-phase screenshot.
+
+Still boxed: the temperature and gravity indicators, and a few trailing status
+icons. Two causes — U+1F321/U+1F525 are supplementary-plane emoji, which the
+legacy fontconfig fallback does not appear to reach, and U+23AF exists only in
+Noto Sans Math / Noto Sans Symbols on this system.
+
+*Ruled out, do not retry:* adding "Noto Sans Symbols" (no 2) for U+23AF. Its
+family name is a prefix of "Noto Sans Symbols2" and the parser mis-resolves
+between them — basic punctuation (`/ : ,` parens) turns to boxes and the armor
+pips disappear. Also ruled out earlier: trusting MegaMek's `data/fonts` alone,
+which removed all font-load rejections but fixed nothing.
 
 **Open fullscreen** — the frame opens small inside a large viewport. Webswing
 already passes `webswing.screenWidth`/`screenHeight` to the app JVM.
