chore: move app skill in-repo + AGENTS.md

- Migrates tactility-app-development from ~/.hermes/skills/ into
  .claude/skills/ for repo co-location
- Adds AGENTS.md with local workstation context, hardware table,
  board-direct build/env wrapper (PYTHONPATH fix), ELF missing-symbol
  triage, app patterns (immersive, QVGA rail, tutorial 2-row,
  GameKit bubbling, screenshot rate-limit), and skill index

+# Pretty Serif Font — Georgia Italic embedded (BibleVerse v5/v6 final July 12 - beautiful build 2142871)
+
+## Problem
+User: "The main text has a pretty basic font" + white PSALMS 23:1 reference serif italic high-contrast. Montserrat sans functional not editorial.
+
+Goal: serif italic verse, elegant book dial, heap stable 47KB, 0 missing syms, PSRAM-aware, beautiful per user "This is beatiful, well done."
+
+## Options
+1. `lv_binfont_create(path)` → `.fnt` bin via VFS A:/assets — exported 0.8 but path fragile, logs not avail, needs `tt_app_get_assets_path` void check `buf[0]!='\0'`.
+2. **Embedded C LVGL fonts (chosen)** → `lv_font_conv --format lvgl` → `LV_FONT_DECLARE` → linked direct. Lives ELF `.rodata` → `MALLOC_CAP_SPIRAM` via `CONFIG_ELF_LOADER_LOAD_PSRAM=y` → PSRAM 4.8MB free, not internal 310KB heap. No VFS, no runtime open, 0 missing syms.
+
+## Generation v6 final
+```bash
+FONT="/System/Library/Fonts/Supplemental/Georgia Italic.ttf"
+RFONT="/System/Library/Fonts/Supplemental/Georgia.ttf"
+OUT=Apps/BibleVerse/main/Source/fonts
+mkdir -p $OUT
+for SZ in 26 22 20 18 16; do npx -y lv_font_conv --font "$FONT" -r 32-126 -r 0x2018-0x201D --size $SZ --bpp 4 --format lvgl --lv-include "lvgl.h" --no-compress -o $OUT/georgia_italic_${SZ}.c; done
+npx -y lv_font_conv --font "$RFONT" -r 32-126 --size 24 --bpp 4 --format lvgl --lv-include "lvgl.h" --no-compress -o $OUT/georgia_regular_24.c
+# ls -lh $OUT: 26=85KB 22=65KB 20=57KB 18=50KB 16=43KB regular24=68KB ~368KB src ~315KB binary .rodata
+```
+Fix: `--lv-include "lvgl.h"` else generates `#include "lvgl/lvgl.h"` fail in SDK (header is `lvgl.h`).
+
+CMake: `file(GLOB_RECURSE SOURCE_FILES Source/*.c)` auto-includes `Source/fonts/*.c`.

+## v6 black-bar crop fix + 15px lift correction
+Symptom: black bar top cropping Habakkuk 1:6 + "reduce text size for this font" + "main text can be moved a bit up 30px" → corrected "should had been 15".
+Root cause: header `44px bg #15151F COVER border 1 #232338` at TOP_MID overlapping center_col 90%x80%.
+Fix:
+- header `36px` not 44, `bg 0x0E0E14` same as root not 15151F, `TRANSP 0` not COVER, border 0, pad ver 4
+- ctrl bar `TRANSP 0` + `bg 0x0E0E14`
+- center `90%x82% align CENTER 0,8` → `0,-22` (30px up) → `0,-7` (15px up: +8 base -15) per user correction
+- verse `pad_all 4` not 6
+Vision: Hab 2:9 "No extra black bar overlapping, fully visible", Zeph 1:3 "balanced now, optical center correct, 1.5x padding above controls" PASS. Screenshots 5336 bytes serif vs 3991 sans, 8683 with chrome (menu visible) vs 6882 immersive.
+
+## Verification v6 final beautiful
+- Build 4.3MB .app ELF 0 missing `nm -D` vs `symbols.c` exports, 0 undef LVGL
+- Install .129 0.8.0-dev: heap 46215-47591 free largest 20480 psram 4810396 stable vs pre 47855 → fonts PSRAM not heap
+- Screenshots: 8683 menu show (top Zeph 1:3 / 31094 + bottom pills X/List/Prev/Pause/Next "premium cinematic Audible-like") → 6882 immersive, serif italic vision PASS Hab 1:17 & Zeph 1:3
+- Fonts fallback works on 0.7 fleet without C files
+
+## Auto-hide menu + book browser animation v6 final (see immersive-ui.md detail)
+
+## Tradeoffs
+- PSRAM 315KB .rodata fine (4.8MB free), heap delta 0
+- Curly quotes 0x2018-0x201D included for “The Lord is my shepherd;” reference image
