1.5.0.22-dev1-cpr-vcodex-steroids

🚀 CPR-vCodex Steroids — Upstream Alignment + Status Bar Enhancements

This release consolidates the full upstream 1.5.0.20–1.5.0.22 alignment into Steroids, plus expands the status bar time display with two new reading-time modes.

📊 Status Bar Time-Left: 2 New Modes (5 total)

The reader status bar now offers 5 options instead of 3 for what to display:

Mode	Shows	What it means
Hide	—	Nothing (as before)
Chapter	Est. time to finish the chapter	Per-book pace from page turns (as before)
Book	Est. time to finish the book	Per-book pace + progress extrapolation (as before)
🆕 Session Duration	Time read since you opened this book	Resets every time you open/close a book. Shows how long you've been reading this session.
🆕 Today Total	Total time read today	Sum of all reading today across all books, including the current session.

The label in settings was renamed from "Time Left" → "Display Time" (EN) / "Tempo rimanente" → "Tempo visualizzato" (IT) since it now also shows elapsed time, not just remaining estimates.

How it works (simplified):

• Session Duration uses the internal reading session timer — it starts counting when you open a book and resets when you close it.
• Today Total reads from the existing daily summary file (summary.json), which already tracks everything you've read today. It includes the current session automatically — no double counting.

Settings → Customize Status Bar → Display Time → cycle through all 5 options. Also configurable from the web interface (/steroids-settings page).

🛠️ What Was Ported from Upstream 1.5.0.20–1.5.0.22

All deferred items from the previous alignment are now resolved:

📟 HAL Crash Detection

• Ported the panic capture mechanism (PANIC_CAPTURE_MAGIC) that distinguishes genuine crashes (watchdog resets with the magic marker set) from normal deep-sleep wake cycles. False-positive crash reports after sleep are now suppressed.
• CrashActivity no longer redundantly clears the panic marker — the HAL handles it automatically after verifying the capture was written completely.

📚 SdCardFont Fragmentation-Resistant Storage (1.5.0.20)

The single biggest technical port — 16 files changed, 800+ lines. The font system no longer allocates one large contiguous buffer for glyphs. Instead:

• 4 KiB chunked storage (24 chunks × 4 KiB = 96 KiB virtual space) — each chunk allocated independently, so only one 4 KiB contiguous block is needed at a time instead of a large buffer. Eliminates render failures caused by heap fragmentation on the 380 KB ESP32-C3.
• CJK fallback font resolution — new hasCodepoint() + coverageHandler on font families automatically picks a font that can render Chinese/Japanese/Korean characters.
• TextGetter prewarm — pre-warms font data before rendering without re-allocating.
• FrameBufferLoan — loans the framebuffer during EPUB section builds, giving the inflate stream a guaranteed ~43 KB contiguous window. Prevents "Failed to init inflate stream" errors.
• FontDecompressor refactor — raw uint8_t* + realloc instead of std::vector, removing lazy-init complexity.

🖼️ Grayscale Image Pipeline (Steroids-specific, unchanged)

• Shared gamma LUT (1.5) + empiric thresholds (50/120/200) + error-diffusion dithering. Already in place.

🔌 Web Server Serial + FirmwareFlasher Chip Validation

• Web server serial number endpoint and FirmwareFlasher now validate the chip target before flashing. Ported from upstream.

🏠 Carousel Recents Panel Fix

• The "Carousel Recents (N)" panel was appearing in the wrong theme. Fixed the guard so it only shows in Lyra Marcoand75, not Lyra Carousel.
• App icon menu slots increased from 5 → 7 (matching Marcoand75).
• Recent books count increased from 3 → 20 (clamped to 10 by the home activity).
