Reading chamber
Look presets, spoiler mode, continue-reading, immersive chrome, and keyboard shortcuts.
The chamber is the public reading surface: home, novel pages, and chapter pages. Appearance is one named look preset that owns color, fonts, type size, measure, and corner radius together. Spoiler mode is independent of the look.
Open the header gear to change both.
Look presets
Comfort (eyes and access):
| Preset | Scheme | Type |
|---|---|---|
| Daylight | Light, warm paper | Literata, easy daylight |
| Dusk | Dark, warm night | Slightly larger type, low blue light |
| Clear | High-contrast light | Atkinson Hyperlegible, larger, wide measure |
| Beacon | High-contrast night | Atkinson on black |
Story (genre atmosphere):
| Preset | Scheme | Type |
|---|---|---|
| Manuscript | Light | Fraunces titles, Literata prose, Bricolage UI. Default |
| Myth | Light | Parchment and Fraunces, high fantasy |
| Starfarer | Dark | Cool night, Source Sans titles, Source Serif prose. Science fiction |
| Nocturne | Dark | Gothic, Fraunces titles, Newsreader body. Horror |
| Lantern | Light | Soft color, round corners. YA, fairy tale, anime |
| Broadsheet | Light | Newsreader columns, sharp edges. Pulp, comics, serials |
The preset is stored in localStorage (sumi:preset). Older split keys (sumi:palette, sumi:type, …) map onto a single preset and are then forgotten.
Spoiler mode
| Mode | Codex indexes | Atlas |
|---|---|---|
| First-time (default) | spoiler cards hidden | Pins stay covered |
| Scholar | Spoiler cards visible | Atlas reveal on |
secret entities are never built, so Scholar mode cannot show them. First-time is the right default for a public serial: the Codex does not leak later volumes from the index.

Opening a chapter writes a pointer: novel, chapter title, href, and scroll position. The home page offers that pointer back. It lives in localStorage (sumi:continue) on the reader's machine — not on the server.
Immersive mode
Press i to hide header and footer. An exit control stays in the corner. The flag is data-immersive on html, persisted as sumi:immersive.
Keys
These fire when the focus is not an input or contenteditable field.
| Key | Action |
|---|---|
j | Next chapter |
k | Previous chapter |
m | Atlas |
i | Immersive on/off |
? | Keyboard help |
Esc | Close overlays |
Home wash
The sample home page sits on a Paper Noir grainient (peach / bark / taupe, slow warp, film grain). Chapter pages use the preset background, not that wash. This studio guide reuses the home wash only on Astro Sumi docs pages.
