## Summary

**What is the goal of this PR?**

Until today, I sincerely thought we were building without exception
support. The codebase is not set up with any exception handling
infrastructure. The SKILL.md file specifies no exceptions.

I just learned that we actually were building with exceptions enabled,
with `-fexceptions` coming from
~/.platformio/packages/framework-arduinoespressif32-libs/esp32c3/pioarduino-build.py.

This change removes the `-fexceptions` flag and adds `-fno-exceptions`.
The result is **53,670 bytes in flash savings**.

* feat: Implement silent pre-indexing for the next chapter in EpubReaderActivity (crosspoint-reader#979)

## Summary

* A simple tweak to pre-index the next chapter silently during normal
reading.
* Triggers silent pre-indexing of the next chapter when the penultimate
page of a chapter is rendered to reduce visible interruptions.
* Keeps existing indexing with popup when a reader jumps directly into
an unindexed chapter.

## Additional Context

* Reader input is temporarily blocked during silent indexing to avoid
navigation/index state conflicts.
* The penultimate page is used because readers typically spend longer
there than on the final page.
* This change optimizes linear reading flow while preserving reliable
indexing for non-linear navigation.

## Possible Improvements

* Add a setting for First Page Indexing vs Penultimate Page Pre-indexing
* Display an indexing icon in the status bar instead of using a popup
that overlaps book text.

Tested on device:

* fix: Fix prewarm perf when a page contains many styles (crosspoint-reader#1451)

## Summary

**What is the goal of this PR?** (e.g., Implements the new feature for
file uploading.)

Fix prewarm perf when a page contains many styles.

The prewarm page buffer was a single slot, so each `prewarmCache` call
for a new font style freed the previous style's glyphs. On pages with
multiple styles (regular + bold + italic), only the last style was
prewarmed. The others fell through to the hot-group compaction path at
~2-3ms per glyph.

This was most visible on rich formatting (e.g. this [Czech prayer
book](https://stahuj.kancional.cz/e-kniha/kancional.epub) with bold
headings, italic liturgical text, and regular body), where page renders
took 3-5 seconds instead of ~700ms.

Fix: use up to 4 page buffer slots (one per font style) so all styles
stay prewarmed simultaneously.

Fixes crosspoint-reader#1450.

* fix: use sleep routine from the original firmware (crosspoint-reader#1298)

## Summary

Fixes crosspoint-reader#1263

I spent half of my day(-off) reverse engineering the stock english
firmware V3.1.1, it's more or less like solving a sudoku with some known
pieces (like debug strings, known static addresses, known compiled
function, etc) and then the task is to guess the rest.

Long story short, this is the sleep routine that they use:

<img width="674" height="604" alt="image" src="/deoxy?target=https%3A%2F%2Fgithub.com%2Fcrosspoint-reader%2Fcrosspoint-reader%2Fpull%2F%253Ca%2520href%3D"https://github.com/user-attachments/assets/6d53ce44-7bae-40c7-b4fb-24f898dbcc05">https://github.com/user-attachments/assets/6d53ce44-7bae-40c7-b4fb-24f898dbcc05"
/>

From the code above:
- They pull down GPIO13 (value = 0xd) before sleep
- They verify that power button is released by doing a delay loop of
50ms, similar to what we're doing
- `esp_sleep_config_gpio_isolate` is called but I'm not 100% sure why
- Pull up power button, note that it's likely redundant because power
button should already pulled up by `InputManager`
- `param1` and `param2` means enabling front/side buttons for wake up,
but it doesn't used in the code in reality. But I think it's physically
impossible, see the explanation below
- `param3` means "wake up from power button"
- `esp_sleep_start` is used; there is a logic to handle if it fails to
sleep, then retry recursively (no idea why!)

My observation is that they use GPIO13 so that it will be on HIGH state
when the chip is powered on, without any user space code to keep it on
that state. And once going to deep sleep, it goes into FLOATING by
default. That may explain why it need to be in LOW state before going to
sleep. (Nice trick btw)

Looking again at the circuit diagram provided
[here](https://github.com/sunwoods/Xteink-X4/blob/main/readme-img/sch.jpg)
(note: it's not official):

<img width="705" height="384" alt="image" src="/deoxy?target=https%3A%2F%2Fgithub.com%2Fcrosspoint-reader%2Fcrosspoint-reader%2Fpull%2F%253Ca%2520href%3D"https://github.com/user-attachments/assets/b98d59fd-47ca-4d3d-a24a-94bf999e957b">https://github.com/user-attachments/assets/b98d59fd-47ca-4d3d-a24a-94bf999e957b"
/>

It kinda make sense as the GPIO13 and VBUS (USB VCC) have the same role,
they are part of a simple "battery protection" cirtuit

Now, we may wonder, how the device wake up when there is no battery at
all?

<img width="440" height="323" alt="image" src="/deoxy?target=https%3A%2F%2Fgithub.com%2Fcrosspoint-reader%2Fcrosspoint-reader%2Fpull%2F%253Ca%2520href%3D"https://github.com/user-attachments/assets/2981c411-239b-49a7-b9f7-9a75b6c1b6d3">https://github.com/user-attachments/assets/2981c411-239b-49a7-b9f7-9a75b6c1b6d3"
/>

It seems like power button is not just a simple switch between GPIO3 and
ground, but it also linked the POWER_CTRL, which leads to nowhere on the
diagram, but I suppose it connects the battery back for a short amount
of time, just enough for the MCU to wake up, and GPIO13 goes HIGH again.
It may also explain why power button becomes non-responsive for ~1
second after power on, as it's being pulled up by the current from
battery (remind: high = not pressed, low = pressed)

To test the theory above, I simply **comment out** the
`esp_deep_sleep_enable_gpio_wakeup`:
- On battery, power button works as nothing happen
- On USB, it doesn't wake up, I need to press RST

---

Important things about my analysis:
1. I had to name every function on the code above **manually**, but I'm
99% confident about it. The only function that I'm not sure is
`esp_wifi_bt_power_domain_off` ; Edit: it was indeed mislabeled, see
crosspoint-reader#1298 (comment)
2. Some logic inside the stock firmware looks very strange, there is
almost no mention to "arduino" in the hardware, suggesting that they may
just call esp-idf functions directly, bypassing the arduino abstraction.

* feat: integrated epub optimizer (crosspoint-reader#1224)

## Problem

Many e-ink readers have limited image decoder support natively.
EPUBs with images in other formats than **baseline JPEG** frequently
cause:

- **Broken images**: pages render as blank, corrupted noise, or never
load
- **Slow rendering**: unoptimized images cause severe delays on e-ink
hardware, up to 7 seconds per page turn, with cover images taking up to
59 seconds to render
- **Broken covers**: the book thumbnail never generates

Fixing this today requires external tools before uploading.

---

## What this PR does

Adds an **optional, on-demand EPUB optimizer** to the file upload flow.
When enabled,
it converts all images to baseline JPEG directly in the browser — no
server, no internet,
no external tools needed.

**Conversion is opt-in. The standard upload flow is unchanged.**

---

## Real-world impact

The optimizer was applied in batch to **61 EPUBs**:
- 60 standard EPUBs: 198 MB → 55 MB (**−72.2%**, 143 MB saved)
- Text-dominant books: 8–46% smaller (covers and inline images
converted)
  - Image-heavy / illustrated books: 65–93% smaller
- 1 Large manga volume (594 MB): 594 MB → 72 MB (**−87.8%**, 522 MB
saved)
- EPUB structural integrity fully maintained — zero new validation
issues introduced across all 61 books

*Size and integrity analysis:
[epub-comparator](https://github.com/pablohc/epub-comparator)*

From that set, **17 books were selected** as a representative sample
covering different content
types: image-heavy novels, pure manga, light novels with broken images,
and text-dominant books.
Each was benchmarked on two devices running in parallel, one on `master`
and one
on `PR#1224` — measuring render time across ~30 pages per book on
average.

## ⚠️ Known limitations

**KoReader hash-based sync will break** for converted files. The file
content changes,
so the hash no longer matches the original. Filename-based sync is
unaffected.

If you rely on KoReader hash sync, use the Calibre plugin or the web
tool instead.

* fix: Fix img layout issue / support CSS display:none for elements and images (crosspoint-reader#1443)

## Summary
- Add CSS `display: none` support to the EPUB rendering pipeline (fixes
crosspoint-reader#1431)
- Parse `display` property in stylesheets and inline styles, with full
cascade resolution (element, class, element.class, inline)
- Skip hidden elements and all their descendants in
`ChapterHtmlSlimParser`
- Separate display:none check for `<img>` tags (image code path is
independent of the general element handler)
- Flush pending text blocks before placing images to fix layout ordering
(text preceding an image now correctly renders above it)
- Bump CSS cache version to 4 to invalidate stale caches
- Add test EPUB (`test_display_none.epub`) covering class selectors,
element selectors, combined selectors, inline styles, nested hidden
content, hidden images, style priority/override, and realistic use cases

* fix: Overlapping battery percentage on image pages with anti-aliasing (crosspoint-reader#1452)

## Summary

**What is the goal of this PR?**

When viewing a page with images and anti-aliasing enabled, the
`imagePageWithAA` path renders the page twice with fast refreshes (blank
image area, then restore). Both passes called `renderStatusBar()`, which
reads the battery percentage live. If the value changed between the two
renders (e.g. 88% -> 87%), the digits would overlap on screen.
Fix: Removed the redundant `renderStatusBar()` from the second BW
render. The status bar is already drawn and displayed in the first pass,
and only the image area needs restoration.
