Split on screen text config into three placeable pieces. The text used to be one combined string — PAGE 1/1 N CHARS F3=SEARCH — drawn at a single spot. they are now three independent, positionable Style elements:

• pageReadout -> PAGE n/n
• charCount -> N CHARS (new)
• searchHint -> F3=SEARCH, which becomes the active filter (FILTER: RYU, AUTHOR: POTS, TAG: SF) once a search is applied (new)

Fixed tile resizing. Resizing the tiles used to zoom the whole grid, which could push it off its panel and overlap other things. Now it re-flows instead: making tiles bigger just fits fewer per page, making them smaller fits more, and the grid always stays inside the character-select frame dynamically.

Note: this only works on screenpacks that draw their grid slots dynamically. If a screenpack has the slots baked into its character-select background image, those slots can't move or resize - so tile resizing turns itself off automatically on those packs (the grid still displays fine at its normal size).

## Update
Fixed stage select flashing and having a seizure after character selection - thanks to sondi for reporting!
Fixed P2/P3/P4 not being able to search after P1 filters, thus being stuck with the search filter P1 made, broke in last RC.

Added better searching to snap to best character match
Respect user hidden characters
